The main objective of this article is to implement and compare QRS subtraction techniques for intracardiac atrial electrograms based on using the surface ECG as a reference. A band-pass filter between 8 and 20 Hz followed by rectification, and then a low-pass filter at 6 Hz are used for QRS detectio...
