I know that standard ecg has 12 leads, but sometimes on some ecg i see additional strip. what is this is there a 13th lead? could you pls explain

The usual format for: a 12 lead EKG includes a lead II rhythm strip across the bottom of the tracing. That is the strip you are referring to. It is just a continuous lead II not a "13th" lead.
