一、心率的自动检测心率是评价心脏机能的一个重要指标,同时它还能多方面地反映生理机能,所以在病人监护系统中占有重要的地位。心率的检测技术目前已比较成熟。既能得到瞬时心率也能得到平均心率,精度都超过了人工检测,所以得到广泛的应用。心率的自动检测是基于测量与心搏同时发生的生理信号。常用的有心电和动脉波。心电的检出是大家都熟悉的。心脏的电活动与心脏的机械搏动是完全同步的。心电中最容易检出的是QRS波,即使在早跳等心搏出量少的情况下也能测出,所以是比较 First, the automatic detection of heart rate Heart rate is an important indicator of cardiac function, but it also reflects the physiological functions in many ways, so occupy an important position in the patient monitoring system. Heart rate detection technology is now more mature. Both instantaneous heart rate can get the average heart rate, the accuracy of more than manual testing, it has been widely used. The automatic detection of heart rate is based on the measurement of physical signs of heartbeat. Commonly used ECG and arterial waves. ECG detection is familiar to everyone. The electrical activity of the heart is completely synchronized with the mechanical pulsation of the heart. ECG is the easiest detection of QRS wave, even in the early jump and other cardiac output can be measured less, it is compared
