Embodiment Construction
[0056] In order to make the purpose, features and effects of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0057] Many specific details are set forth in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways than described here, so the present invention is not limited by the specific embodiments disclosed below.
[0058] This embodiment provides a heart rate acquisition method, such as figure 2 shown, including:
[0059] Step S100, recording the moment when the R wave appears on the ECG waveform.
[0060] In this step, the ECG signal waveform is generally based on the immediately input ECG signal data. Since the R wave is the most significant wave in the entire ECG signal waveform and its periodicity is relatively stable compared ...

The invention relates to a heart rate acquiring method and an electrocardiosignal processing method. The heart rate acquiring method comprises the following steps of recording moments when an R wave appears on an electrocardiosignal waveform; on the basis of the moment TRi when the R wave appears for the ith times and the moment TRi-1 when the R wave appears for the i-1th times, acquiring an instantaneous heart rate at the moment TRi. The electrocardiosignal processing method comprises the following steps of on the basis of an input electrocardiosignal, acquiring the heart rate at the moment TRi by utilizing the heart rate acquiring method; processing the heart rate at the moment TRi. According to the technical scheme adopted by the invention, the heart rate can be more accurately acquired and real variation of the heart rate is reflected.
Description
technical field [0001] The technical solution of the present invention relates to information processing of electrocardiographic signals, in particular to a method for acquiring heart rate and a method for processing electrocardiographic signals. Background technique [0002] ECG signal, also known as ECG (ECG is the abbreviation of electrocardiogram) signal, is the heart in each cardiac cycle, excited by the pacemaker, atrium, and ventricle successively, accompanied by changes in bioelectricity, through the electrocardiograph from the body Tables lead to graphs of potential changes in various forms. When an individual's heart beats, electrical signals flow through the heart, which can be picked up by suitable devices attached to the individual's skin. A typical and complete ECG signal includes a complete waveform that is considered to be composed of P waves, Q waves, R waves, S waves, and T waves, where Q waves, R waves, and S waves are sometimes collectively referred to a...
