Using what data?
For an EKG, use findpeaks to find the R-deflections, then make appropriate use of the ‘locs’ output to calculate the time between R-deflections, and from that, heart rate.
I leave the details to you.

It is calculated by sound with a microphone and calculated by the sound waves of the heart

In that situation, it will be necessary to use an appropriate filter, and likely the envelope function, with findpeaks or islocalmax to determine the peaks. The loudest and most distinctive will be the first heart sound (generally mitral valve closure) and then the second heart sound (pulmonary and aortic valve closure, that will almost always be slightly different in time, even in a healthy heart, known as ‘physiological splitting’). These are generally relatively high frequency, so choose the appropriate bandpass filter design.
