If the sampling rate of the ECG machine is 1000, that is, 1000 data is sampled every second, how can we calculate the heart rate based on the sampled data? Computing the heart rate with a computer can give full play to the powerful computing power of the computer, so you don't have to wait a minute to get the results, just like the artificial heart
