Method and device for discriminating irregular heartbeat

Abstract

The invention is concerned with a method to judge the heartbeat and its equipment, it measures the heartbeat to judge whether the heartbeat is anomalistic and the measuring unit measures the blood press of the measured person in certain time. The EMS memory of control unit memories the number of heartbeat and pulse wave and the time differences between two stored pulse wave and add up the number of pulse wave's time. The microprocessor accounts the average time of pulse waves and the number of heartbeat according to the parameter. Take the first step judge according to the said results to estimate whether the number of pulse wave during the checking period is enough to judge the heartbeat is or is not anomalistic. If the condition is coincidental, take the second step judge and compare the time difference between closed pulse wave and the time of average pulse wave. When the exceptional ratio reaches at the advance heartbeat, the display will shows the anomalistic signal of heartbeat and it improves the high error ratio by advanced standard value.

Description

technical field [0001] The present invention relates to an electronic sphygmomanometer, in particular to a method and device for judging irregular heartbeat as follows, wherein the pulse wave number is simultaneously recorded during the blood pressure measurement of the subject within a certain period of time. Under the condition of judging irregular heartbeat, judge whether the measured person has irregular heartbeat. Background technique [0002] According to relevant medical reports, more than 90% of patients with sudden death are caused by rapid ventricular tachycardia or ventricular fibrillation, so the measurement and judgment of irregular heartbeat (also known as irregular heartbeat) symptoms are the key to preventing heart disease an important parameter. [0003] It is known that at present, the measurement of irregular heartbeat is checked and judged by the electrocardiogram recorder (Hotter's electrocardiogram) and the electrocardiogram, and the inspection of the ...

Problems solved by technology

[0006]The above-mentioned patents all compare and judge the measured ECG signal or heartbeat pulse wave signal with the preset standard value or comparison condition generated according to the medical research results, However, this standard value will generate an average parameter value from statistical results, and the heartbeat characteristics of each measured person are different. Therefore, in terms of specific measurement parameter comparison, it is not applicable to every measured person, and it is preset by the standard value It is easy to cause errors in judgment, which in turn affects the judgment results.
