Hello I Have ESG signal vector (for one row and multiple columns)
for example my ecg value contain
[4.61607668632528e-06 5.05138279253496e-06 5.98780349369488-06]
and I want to Know that my ecg signals is good or bad from the value of the ecg How I Know that ??
can you help me please
If I can measurement that from the calculate the rate how can I do that??

You ECG signal is in microvolts. In my experience that is a very small amplitude for ECG.
It is definitely a reasonable level for EEG signals recording with electrodes from the scalp. However, the heart being a muscle usually produces a much larger electric potentials at the surface electrodes, typically on the order of millivolts.
Are you sure this is ECG and not EEG?

that is a very small amplitude ECG then. You can calculate heart by looking a number of ways: 1.) use a Fourier transform, 2.) use xcorr

I tray to using xcorr
put making error :\
my code is :
chekingX= xcorr(chekingX1);
chekingX1 is my ecg vector size is 1 2500 (one row and 2500 columns)
Pleazzzzzz help me "(
