Before you complete this step, you HAVE to go back and read about data cleaning!
To export an excel spreadsheet with cardiac data, go to Analysis → ECG interval extraction → select CH9, ECG → excel spreadsheet only → ok
The resulting spreadsheet contains beat-to-beat R-R intervals (time in seconds between two cardiac cycle peaks) and heart rate for each cycle.
1. Import into Matlab
This is to plot the shape of the cardiac response curve.
2. Compute variables across the whole task period
This is mostly relevant for Rest and Meditation, where there are no challenge responses.
