Patent ID: 7797039

Claim:
Method for recognizing and measuring heartbeat during physical training, comprising: recognizing individual heartbeats from ECG signals of a heart from an area of a waist and/or on an area of a body below the waist by means of electrodes integrated into an outfit or to a part of an outfit and/or by means of electrodes integrated to one or several wearable sensors, which electrodes are placed on different parts of the body measuring two or more of the ECG signals received from the heart simultaneously from different directions from the heart by means of three or more of said electrodes for recognizing the individual heartbeats and measuring a time difference between the individual heartbeats, comprising receiving at least two of the ECG signals of one of the heartbeats which are simultaneous but differ from each other, processing and analyzing the ECG at least two different ways to highlight moments of QRS peaks of the heartbeats for improving reliability of calculation and for decreasing impact of disturbances, processing the ECG signals, taken from a moving person for analysis, by means of information from simultaneously measured EMG signals of this moving person decreasing influence of muscle noises.
