Battery life: over 96 hours
Charging: Charger dock or USB interface
Continuous recording time: 24 hours
Connection to PC: USB

Heart rate variability measurement:
Sampling frequency: 1000 Hz
Accuracy: 1 ms

Special features only in eMotion HRV:

Sampling frequency of eMotion HRV is 1000 samples per second giving great measurement accuracy of 1ms. Rechargeable battery and large internal memory enables measurements as long as 5 days. Data from the memory is downloaded easily through USB-connection.
• Compact and lightweight
• Easy to use (single button operation)
• Comfortable to wear (also during sleep)
• Long measurement time
• Accurate measurements
• Less artefacts than in chest strap measurements
• Superior conductivity between skin and sensor
• Easy charging for multiple sensors
• No need for wrist top computer
• Unnoticeable during daily life

Overcomes common problems related to chest strap measurements:
In eMotion HRV measurement artefacts and interruptions are effectively eliminated with high-end technology and disposable surface electrodes. As there is no need for a strap around the chest, eMotion HRV overcomes all common problems and disadvantages associated with chest strap based measurements:
• Measurement artefacts created by movements of chest strap
• Measurement artefacts created by drying of the electrode surfaces
• Discomfort associated in long ambulatory measurements
• Need to use additional device like wrist-top computer
• Altered behaviour due to visual feedback of heart rate in research projects

Original software from Mega Electronics

eMotion LAB software

eMotion LAB software is designed for downloading, viewing and easy exporting of HRV data.

HRV-Scanner software

HRV-Scanner is a complete HRV biofeedback system with animated 3D biofeedback and real time spectral analysis. With the HRV-Scanner software and eMotion HRV sensor you can do both Short-term HRV tests and Long-term HRV analysis. HRV-Scanner is available from our web store.

Third party software for eMotion HRV

eMotion HRV data can also be analyzed with following software.

Kubios HRV software

For research purposes R-R data, for example, can be analyzed with a freely distributed Kubios HRV software (developed in Department of Applied Physics, University of Eastern Finland, Finland; available at http://kubios.uef.fi). This comprehensive software offers easy-to-use graphical user interface with automated and customizable calculation settings. Analysis options include several common time-domain, frequency-domain and nonlinear HRV measures. Software includes also R-R interval artefact correction and advanced detrending options for removal of disturbing low frequency baseline trend components. Practical PDF report sheets are produced automatically and results can be exported in ASCII format.

Firstbeat SPORTS software

Firstbeat SPORTS software is designed for:
• Training centers
• Physical conditioning coaches
• Sports medicine clinics
• Fitness testing centers
• Sports research centers
The method is based on advanced analysis of beat-by-beat heart rate data and especially heart rate variability. The software has been successfully applied to support training in many different sports including ice hockey, soccer, track and field, shooting sports, volleyball, swinmming, cross-country skiing and more. It is best suited for all endurance sports.

The key benefits of Firstbeat SPORTS are:
• Indicate overtraining
• Indicate undertraining
• Allow individually optimized training
• Monitor athletes fitness level
• Support critical coaching decisions
• Maximize recovery between two training sessions

Firstbeat HEALTH software

Firstbeat HEALTH is easy-to-use software tool for heart beat analysis. The solution is developed for the needs of work-related research, occupational health care and applied physiological research.

Firstbeat HEALTH software is designed for applied research and field measurements in situations where accurate information on physiology is needed but the use of obstrusive methods is not desired.

The method is easy to apply as only beat-by-beat (R-R) recording of heart rate is required. Although the data collection procedure is simple, the method is capable of producing meaningful physiological information by deploying advanced heart beat data analysis. This unique and highly developed heart beat analysis enables monitoring of several physiological parameters by using only beat-by-beat heart rate sensor.

eMotion HRV 3D

Mega Electronics Ltd introduces the most reliable and convenient way to measure heart rate variability (R-R intervals) and acceleration. eMotion HRV 3D is an ideal solution to be used in obesity research, epidemiology, stress monitoring sports medicine and in top sports.

Features

• Heart rate variability and 3-axis accelerometry with one device
• Sampling and recording with high frequency
• Ideal for ambulatory measurements

Applications:

• Sports medicine and exercise science
• Obesity research
• Stress monitoring
• Epidemiology

Special features only in eMotion HRV 3D:

eMotion HRV 3D is the smallest and most practical device for accurate measurements of both HRV and acceleration.

Sampling frequency of heart rate variability is 1000 samples per second giving great measurement accuracy of 1ms for HRV. Data from the memory is downloaded easily through USB-connection.

1. Accurate measurement of HRV and acceleration with single device
2. Records raw data and not only epochs like most other devices
3. Compact and lightweight
4. Easy to use (single button operation)
5. Comfortable to wear (also during sleep)
6. Long measurement time
7. Less artefacts than in chest strap measurements
8. Superior conductivity between skin and sensor
9. Easy charging for multiple sensors

Advantages of simultaneous acceleration measurement:

• Physical activity can be monitored more accurately
• Ambulatory activities can be detected from the data
• In HRV measurements acceleration data can be used to complement activity diary
• More accurate algorithms for energy expenditure can be used
• Changes in posture can be detected from data
