Problems solved by technology

[0007] The purpose of the present invention is to provide a method for automatically starting the electrocardiogram record of a hand-held electrocardiogram detector. This method can solve the problem that the current electrocardiogram equipment needs to be manually started when recording the electrocardiogram, especially for hand-held equipment, when manually starting, there will be problems. Introduce a lot of interference to the ECG waveform, resulting in the distortion of the recorded data, which is not easy to analyze

Embodiment Construction

[0027] In order to realize a hand-held ECG detector to automatically open the ECG record, solve the problem that ordinary patients can use the hand-held ECG detector in the absence of medical staff, and can be used alone to automatically sense the human body and electrodes by detecting whether the lead is off. Start pre-acquisition according to the contact state; also can add setting threshold to remove some interference waves to find the R point of ECG pulse; this embodiment adds stability discrimination on the basis of the above.

[0028] The introduction of stability discrimination realizes an intelligent pre-acquisition analysis, which is used for pre-analysis of acquisition waveforms. Through the differential square integral amplification of the waveform and the dynamic adjustment of the prediction, the R point of the ECG pulse is clearly found, and then the R-R interval is compared and judged to judge whether the ECG acquisition has started according to the judgment resul...

Abstract

The invention discloses a method for a handheld electrocardio detector to automatically start electrocardiogram recording. The method comprises the steps of judging whether an electrode disengages through an acquired signal, judging whether an interference signal in electrocardiogram signals exceeds a set value through the acquired signal, and judging whether the electrocardiogram signals are stable. According to the method, by adding stability judgment, interference waves are further filtered out, the R-R interval judgment method is adopted for stability judgment, waveform interference situations such as weak signals and severe interference are effectively eliminated, analysis of various waveforms such as normal electrocardiogram waveform and bigeminy, trigeminy, quadrigeminy waveforms can be achieved, and finally high-quality, low-interference and effective electrocardiogram waveforms are acquired and analyzed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method for automatically starting electrocardiogram recording by a hand-held electrocardiogram detector. Background technique [0002] Hand-held ECG detectors have entered thousands of households and people's lives, and are an important tool for people to carry out daily ECG monitoring. The electrocardiogram and heart rate are one of the important medical indicators that reflect the health of the human body. They are also one of the important basis for daily ECG monitoring, guiding people to develop correct work and rest habits, and guiding athletes to scientific training. Heart rate is generally defined as the The number of times a human heart beats in one minute. The hand-held ECG detector can not only measure ECG quickly, real-time and conveniently, but also is very convenient to carry, which can realize ECG detection anytime and anywhere. [0003] At present, the commonly...
