An example of the P wave detection procedure and the application of decision rules in the case of an ECG signal with PVC. In the first stage (left image), four P waves (before QRS complexes) are found. In the second stage, the third P wave is deleted due to the first decision rule; the third beat (R(i)) is PVC, which means that the P wave detected during the basic P wave detection R(i) is deleted. The remaining criteria (marked with x) were not checked further.
