There is a label called EKG_Off in edf file in MESA database. I am confused about using it to detect to EKG lead-off condition. Could you give me some advices to detect the EKG lead-off condition in MESA database?
"_Off" signals are lead detection channels. If the signal is above or below a pre-set threshold, then either the positive or negative lead of the channel has come off. If values are reading within the preset ranges, the lead is considered valid. These channels are specific to the manufacturer, and further details are not disclosed in their specifications.
