Data Analysis

G Valenti

• HR calculation from ECG

Average of the interval between the first and the last beat in a time window of 7 seconds.

Interpolation and re-sampling (1Hz)

• Synchronization of OHRM and Polar with the ECG (High-pass filter and correlation)

• ECG was the reference to calculate the OHRM Error and the Polar Error.

Conclusion

Introduction Methods Results Conclusion

The OHRM is a valid and unobtrusive device to monitor heart rate, not restricted by movement artifacts during physical activities including running, allowing monitoring cardiovascular condition in response to fitness and home health care activities. There are evidence of a positive effect of BMI on OHRM precision.
