由心电图的r波到血氧浓度图的波峰所产生的脉波传递时间换算出脉波传递速度,进一步换算出血压的变化量-R wave from the ECG to the peak oxygen concentration diagram of the pulse wave generated by the time translation of the pulse wave velocity, and further converted from the change in blood pressure

一种ECG检测的算法，主要是检测R波及其坐标-One kind of ECG detection algorithm, mainly R wave detection and coordinate
