mathematical formula(The last R wave position-the first R wave position) is the number of data records between the last R wave and the first R wave. If the sampling rate is 1000, this value is actually the number of milliseconds.(R wave count-1) the number of Heartbeat cycles that have elapsed in so many milliseconds. Why minus one? Suppose there is a two-dimensional wave spreading along the X axis. How many fluctuation periods are there between two
