# Explanation of Symbols

Caution

Caution.

Read the manual and the safety instructions to find out about possible hazards and the needed actions to avoid these hazards!

# Scope of Application

EcgMove 4 is a scientific research instrument that captures the ECG, physical activity, and other secondary parameters derivable from these measurement signals. EcgMove 4 is designed and tailored for use in research applications.

The ECG and physical activity sensor EcgMove 4 is not a medical device!

The sensor acquires a single channel ECG signal and can be used with a dry electrode chest belt or with disposable electrodes. In addition to capturing the ECG signal, the sensor records the physical activity of a person through the acquisition of acceleration in three dimensions, the angular rate (gyroscope) and atmospheric air pressure. Moreover the ambient temperature is acquired.

The sensor configuration occurs via a USB connection to a Windows PC using the Sensor Manager software included in this package.

EcgMove 4 allows the measurement of the following parameters:

  • Electrocardiogram

  • Acceleration in three dimensions

  • Angular Rate

  • Atmospheric Air Pressure

  • Temperature

  • Marker

  • State of Charge

    In conjunction with movisens DataAnalyzer the offline calculation and analysis of the following parameters is possible. In addition to these parameters, reports can be generated.

  • Heart rate and heart rate variability

  • Movement Acceleration and Step Count

  • Activity Classes and Body Position

  • Energy Expenditure

  • Reports

In addition to the offline calculation, EcgMove 4 offers the possibility of a live analysis of ECG and physical activity, and in conjunction with movisensXS - the software platform for experience sampling and the Sensor Trigger - the realization of interactive ambulatory assessment strategies. In live mode, the following parameters can be measured, calculated and transmitted via Bluetooth Smart interface:

  • Movement Acceleration

  • Step Count

  • Heart Rate

  • HRV RMSSD

  • HrvIsValid

    These values are transmitted with 1 value per minute. Additional live parameters will be available soon.

    Heart Rate is transmitted for every heart beat with a delay of 90 seconds.

    HRV and Movement Acceleration are calculated in segments of 30 seconds. The transmitted value is the mean value of two segments.

    Parameters that are marked with “(Bluetooth)” are only transmitted over Bluetooth interface, they are not stored on the sensor.

steps to use the sensor

The right side of the diagram illustrates the process to prepare and run a study on movisensXS.

To retrieve the data from the EcgMove 4, you have to read out the sensor after the measurement. The results of movisensXS only contain the sensor information that causes a trigger.

# Charging the Sensor

Step 1: Connect the cradle with the USB cable to a USB port (USB port of your computer or another port that conforms to USB standard like USB hub or USB charger). Attach the sensor with the help of the push buttons at the cradle. Please make sure that the 4 contacts are connected (marked red in the picture). To charge multiple sensors at the same time, we suggest using a USB hub (see 4.2).

contacts of the sensor and cradle

  • After connecting the sensor to a USB port, the charging process starts immediately. During charging, the status LED is blinking blue. If the sensor is fully charged, the LED is blinking green. The charging process of the sensor can take up to two hours, depending on the battery status of your sensor.

  • If the sensor is fully charged, the battery run time during recording is 3 days.

    Step 2: To extend the measurement duration you can recharge the sensor during a measurement.

  • If recharging during a measurement DO NOT plug the sensor into your PC as that will stop the measurement. Instead use a USB charger.

    When recharging the sensor please ensure that the battery is fully charged (until the sensor is blinking yellow).

  • To be sure that the sensor is not running out of battery, you must advise the test persons to recharge the sensor every day until it is blinking yellow. The time for daily recharging the sensor is about 15 minutes.

    If you recharge the sensor regularly you can make a measurement up to the maximum recording capacity of the sensor of about 2 weeks.

    If the sensor runs out of battery lifetime during a long measurement, the recording of data will be stopped. The measurement won’t be continued even if you connect it to a charger.

    If the sensor is discharged completely (e.g. after a long period where it was not used), it can take up to several minutes until the sensor reacts and can be identified by the computer.

    You can control the battery status before the measurement with the sensor manager, see the following section.

# Preparing a Measurement

Before conducting a measurement please make sure you installed the software as described before.

Step 1: Start the SensorManager by selecting
Windows Startmenu => movisens SensorManager => SensorManager

  • SensorManager is now searching for available sensors.

    Screenshot SensorManager Searching Sensor

Step 2: Connect the EcgMove 4 sensor to your PC using the cradle.

  • The software will automatically detect the device and open the following window:

Screenshot SensorManager

This application shows information about the sensor, parameters that are measured and the last measurement.

Before you start a measurement please check the charging status of the battery. The maximum measurement duration can only be reached when the battery is fully charged.

  • When connecting for the first time allow up to 30 seconds for the device to be detected, as it must first install the necessary driver.

# Starting a Measurement

To start a measurement, please perform the following steps:

Step 1: In the SensorManager software click on the „Start Recording“ button in the lower left of the window.

  • You can see the following window:

Screenshot EcgMove 4 Measurement Configuration

If the battery level of the sensor is less than or equal to 10 % when clicking on the „Start Recording“ button, the following message appears.

Screenshot SensorManager Battery Low

Please connect the sensor to an USB charger!

Step 2: Configure the measurement:

  • Measurement duration: The maximum measurement duration of the EcgMove 4 is about 3 days without recharging the sensor.

  • Start time: You can start the measurement immediately or delayed at a specific time. If you want to start your measurement delayed please specify the date and time. The given time should not be more than 2 days from now as the maximum measurement duration can be influenced.

You have the possibility to enable the Bluetooth interface of the sensor during the measurement by clicking the checkbox.

You can enter the personal information of the proband. This information can also be entered when storing the data after the measurement. For some of the parameters that can be calculated live on the sensor during the measurement, the additional information about the person and the sensor location is mandatory.

The age of the person can be calculated from birthdate. To do this, you have to enter the birthdate and press the “<” button.

If the sensor is used for the second time with the same proband and the personal data was stored before, you can load this data by clicking “Load proband info from Sensor”

Step 3: Start the measurement by clicking the „Start“ button.

  • You will see the following window:

    Screenshot SensorManager Remove Sensor

Step 4: Please follow the instructions and remove the sensor from the cradle.

Step 5: Check if the LED is flashing red

  • The status LED will flash red once per second as soon as the measurement has started and data will be recorded. If a delayed start was configured the LED flashes red every two seconds until the measurement starts.

  • At the end of the measurement the LED stops flashing.

  • If you reconnect the sensor after starting a measurement again with a PC, the following message is shown:

    Screenshot SensorManager Sensor Recording

Please select if you want to stop the measurement, e.g. to read out the data, or if you want to continue measuring.

  • If you connect the sensor to a USB charger, the measurement won’t be stopped. That means you can extend the measurement duration by intermediately charging the sensor during a measurement (see 7.1).

  • If the battery level of the sensor is getting lower than 10 %, the measurement will be paused. The LED stops flashing. You can connect the sensor to a USB charger and recharge the battery. If you disconnect the sensor from charger after battery level is higher than 30%, the measurement will be restarted.

# Attaching the Sensor to the Test Person

Using a chest belt:

Place the chest belt directly on the skin at the level of the participant’s sternum, with the two snap fasteners pointing forward. Adjust the size of the chest belt in order that it cannot slip out of position, but only so tightly that it can be worn comfortably over long periods. Attach the EcgMove 4 sensor to the two snap fasteners. The movisens label on the sensor has to be upright and readable.

  • When adjusting the belt too tight this will result in more artifacts because the belt cannot compensate movements and it will eventually damage the belt.

Using disposable electrodes:

Place two disposable electrodes to each side of the sensor. Attach the electrodes to the test person. The movisens label on the sensor has to be upright and readable.

For both types of electrodes:

  • Shave or cut hair from electrode sites as excessive hair prevents good electrode contact.

  • Clean the electrode sites with oil/grease free soap and water, or with alcohol wipes (e.g. Alcohol Pads, B. Braun).

  • Don’t use body lotions. Oily skin will not conduct clear signals.

  • Due to the dry long-term electrodes in the chest belt, it obtains maximum signal quality in about 15 minutes after putting it on. Therefore please take care to attach the chest belt 15 minutes preceding the acquisition of relevant data. Otherwise strong artifacts can occur in the ECG signal, especially under vigorous movements (e.g. while running).

  • If you use a chest belt, you can shorten the time to obtain a good signal by moistening the electrode areas with water before attaching the chest belt.

  • If you use a chest belt, please wash the belt regularly. For cleaning instructions, see chapter 8.3.

  • If you use adhesive electrodes, you have to thoroughly dry the skin, as electrodes will not adhere to moist skin.

The following figures display the correct location of the chest belt and the electrodes:

Sensor used with chest belt Sensor used with disposable electrodes

# Setting a Marker

Markers can be used in measurements with the sensors to mark specific events. Markers can be set either during or after the measurement. They can be used to annotate the measurement data to better understand what happened during the measurement. They can also be used to mark certain areas that require special attention when analysing the data.

# How to work with markers

1st possibility: marker can be set during measurement. Therfore the user has to tap two times on the front side of the sensor. The sensor vibrates to confirm the successful setting of a marker.

2nd possibility: marker can be set with our Marker Tool request information.

3rd possibillity: marker can be set after measurement within the UnisensViewer (opens new window). Open the measurement with the UnisensViewer tool. If markers already exist, right-click in the marker window and select 'Set marker'. If there are no markers, a marker can be set in any window. Note that the sampling frequency (and therefore the precision of the time definition) depends on the signal in which the marker is set.
Recommendation: Set the markers in the signal with the highest sample rate. A new file will then be created for the markers and a name must be given to it.
Recommendation: The file name should be self-explanatory, e.g. "marker".
Edit marker: Open the file marker.csv with a text editor. A marker (line) consists of a marker type (e.g. M1) and a marker comment (e.g. Start), separated by a semicolon: ⋅⋅*M1;Start;
The name for the marker type should be kept as short as possible. In the UnisensViewer only the marker type is displayed over time, in the sidebar also the marker comment of the marker to the left of the mouse pointer.
Analyse marker:The measurement with markers can be evaluated with the DataAnalyzer. The markers are displayed in the Results.xlsx file.

# Stopping a Measurement

The measurement will automatically be stopped if the configured measurement duration has passed.

A running measurement will also be stopped when:

  • The sensor is connect to a PC

  • The end of the battery run time has been reached

    If the battery is low, this is indicated by fast blue flashing light (three times per second). The sensor will turn off soon.

# Storing Measurement Data

The measurement data of the sensor is stored as raw data (e.g. the acceleration data as it is measured). The data is not processed or aggregated neither in the sensor nor in the SensorManager software. Due to that you have a sustainable database with all the raw data of your study that can be used with future studies and with future algorithms.

To store recorded measurement data on the PC do the following steps:

Step 1: Start the SensorManager by selecting
Windows Start menu => movisens SensorManager => SensorManager

Step 2: Connect EcgMove 4 sensor to the PC using the cradle.

  • After the SensorManager has detected the connected sensor, the following windows will be shown:

Screenshot SensorManager

Step 3: Click on „Save Data“.

  • You will see the following window:

Screenshot SensorManager Save Data

Step 4: Please type in the following information:

  • Select the base folder, where your measurements should be stored. To do this, click the button after the text field.

  • Type in the ID of the measurement. If you want to use date and time in the ID click the “Timestamp” button.

  • If the measurement data shall be further processed with the movisens DataAnalyzer the additional information about the person and the sensor location is mandatory. If you stored the information about the person at the beginning of the measurement, this data will be shown here.

Step 5: Finally click on „Save data“

The measurement data will be stored either in the unisens format or as .csv file. Unisens is an open data format for multi sensor data. You can find further information about unisens here: www.unisens.org (opens new window)

  • If you store the measurement data in .csv format, you can’t analyze the data with the movisens DataAnalyzer.

A unisens data set consists of meta file (unisens.xml) and different data files for each measurement signal. If you store data in unisens format, the following files will be generated:

Screenshot SensorManager EcgMove 4 Files

  • The software confirms the end of data storing process. The following window is shown:

    Screenshot SensorManager Delete Data

You can select if you want to delete the data on sensor. The data on the sensor has to be deleted before you start a new measurement. You can do this now or directly when starting the next measurement.

  • After this, you can select how to continue.

    Screenshot SensorManager Show Data

You can now directly show the stored data. We recommend that you open the data within the UnisensViewer to check for completeness.

This is the default option if you hit enter at this stage. The measurement will be opened in the UnisensViewer. You can use this program to crop and edit the signal, and to make sure that the measurement signal appears clear and intact. More information about the ECG signal is in chapter 8.5

If you have installed the movisens DataAnalyzer you can directly start data analysis and generate reports by clicking on “Analyze data”. You can find more information in the DataAnalyzer User Manual.

# Multipart Measurement

If the measurement was paused because of a low battery level, and continued after recharging the battery, the measurement is stored in multiple parts.

Screenshot SensorManager Multipart Data Structure

In this case, the selection how to continue looks like in the following window.

Screenshot SensorManager Open Folder

If you want to check the measurement data, you have to go to the folder and open the different parts of the measurement with UnisensViewer.

A Multipart measurement can be analyzed with DataAnalyzer by using the batch mode (see DataAnalyzer User Manual). The results of the multiple parts of the measurement can be merged with DataMerger (see DataMerger User Manual)

# Viewing Measurement Data

To view recorded measurements click on „Show data“ directly after storing the data.

To view previously stored measurements use the Windows Explorer to navigate to your measurements folder and then open the folder with the desired ID. Then double click on the “unisens.xml” file. The measurement will then be shown in the UnisensViewer:

UnisensViewer

A first preprocessing of the data can be done with UnisensViewer. You can crop your signal to the desired time, set markers and annotate artefacts. Details can be found in the online help of UnisensViewer.

You directly start the analysis of the data with DataAnalyzer by clicking the “Analyze Data” button.

UnisensViewer

When you open your signal in the UnisensViewer, your ECG signal should look like the following image, containing clear peaks and a defined signal:

signal

When the signal is clear, but contains an unusual waveform it could mean that the electrodes haven’t been placed correctly, or that the sensor has been placed upside down.

The following image shows a signal that had the electrodes incorrectly positioned.

cid:image005.png@01D3CFFD.83B85E90

This makes the signal difficult or impossible to analyze in the DataAnalyzer software.

Other strange signals that are not uniform in nature and contain large volumes of noise could be indicative of a connection issue, either between the sensor and the electrodes, or the electrodes and the skin.

If you’re using disposable electrodes, make sure that they haven’t dried out. Try using a freshly opened set and compare the results.

If the signal doesn’t improve, it could be a connection issue between the electrodes and the skin. Make sure the participant is following the preparation steps detailed in chapter 7.4.

# Analyzing Data

Option:

To analyze the data, movisens offers the modular analyzing software DataAnalyzer. This product is a scientific software application for the analysis of physiologic measurement data. The software is optimized for, but not limited to use with sensor systems from movisens.

With the help of DataAnalyzer, you can calculate secondary parameters from your physiologic measurement data, create summaries and reports. DataAnalyzer can batch-process complete measurement data bases.

DataAnalyzer

After selecting a measurement, DataAnalyzer displays all the possible analysis outputs (secondary parameter and reports). The list of analysis outputs depends on your licensed modules and the data contained in your measurement. You can now select the desired analysis output(s). If you want to select more than one analysis output, keep the Ctrl-key pressed while selecting.

The results of the analysis are stored as a unisens data set. A unisens data set consists of meta file (unisens.xml) and different data files for each measurement signal and secondary parameter. Secondary parameters are stored as .csv files within the unisens data set and can be processed e.g. with Microsoft Excel or SPSS

# Cleaning Instructions

It is important to clean the sensor and the dry electrode chest belts regularly to avoid possible infections between users.
