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?
The RPoint in csv file can't match the r point in edf from mesa database. For example, the first row of RPoint in mesa-sleep-0001-rpoint is 149, but the first r point in mesa-sleep-0001.edf is about 54. My object is to get hrv, brv, cpc features and the corresponding sleep stage label.
Thanks a lot! I should read intro more carefully.
Sorry, i made a mistake. What i mean is the absolute date of actigraphy can not find and the time like MM/DD/YYYY hour/minute of heart rate variability can not find.
Hi team, Body movement and heart rate variability are used together for sleep stage distinguish . However, absolute time of actigraphy can not find. Consquently, there is no idea about the time of actigraphy corresponding to the time of psg(hrv), can I align two kinds of data in time?
