Embodiment Construction

[0036] Some typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description in conjunction with the accompanying drawings. It should be understood that the present invention can have various changes in different embodiments, all of which do not depart from the scope of the present invention, and the description and drawings therein are essentially for illustrative purposes, rather than limiting the present invention. .

[0037] Such as figure 1 Shown is a QRS waveform diagram of an embodiment of the present invention. At point Q, the value of the heartbeat waveform suddenly rises, and the difference suddenly increases in the positive direction. The first difference threshold C1 can be used to detect this point Q. However, the point that meets this condition may also be an accidental fluctuation. In order to ensure that the waveform rises after this point and has a certain height, the height threshold G1 ...

Abstract

The invention discloses a method for measuring the heart rate. The method comprises the following steps of: (1) acquiring heartbeat waveform data and reading the heartbeat waveform data at a first time interval, wherein at least one heartbeat occurs in the first time interval; (b) computing a threshold value according to heartbeat waveform data in at least two latest periods; (c) acquiring heartbeat waveform data in a next period, judging an R wave in a QRS wave group according to the threshold value, and recording the times of the R wave in the period; and (d), judging whether preset detection time is reached, if not, performing the step (b), and if so, counting the R wave times in the preset detection time for serving as heart rate output. The invention further provides a corresponding heart rate measuring system. In the method and the system, comprehensive judgment is made by using segmented self-learning, differences and amplitudes, so that the problems of poor anti-jamming capability, insufficient importance attached to the experience of doctors, computing complexity and / or poor instantaneity and the like are solved, recognition of the R wave can be realized, and the heart rate is further measured accurately.

Description

Technical field [0001] The present invention relates to a method and system for heart rate measurement, and more specifically, to a method for measuring the individual’s heart rate by detecting the QRS complex of the individual’s detected electrocardiogram signal (ECG) and system. Background technique [0002] When the individual's heart beats, electrical signals flow through the heart, which can be acquired by a suitable device connected to the individual's skin. A typical and complete ECG signal includes a complete waveform that is considered to be composed of P wave, Q wave, R wave, S wave and T wave, among which Q wave, R wave and S wave are sometimes collectively referred to as forming a "QRS complex" . Generally speaking, the P wave is generated by the depolarization of the atrium, the QRS complex is generated by the depolarization of the ventricle, and the T wave is generated by the repolarization of the ventricular muscle. Generally, the R wave is the most significant ...
