about ECG signal cheek state

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?

yes ,I am sure and The value I wrote it above is sample of my ecg signals.

The ecg vector size is 1 2500 (one row and 2500 columns)

[Wayne King]

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

[fatimah]

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 "(
