Abstract
In general, this disclosure is directed to signal processing based methods to reject undersensing in a signal indicative of cardiac activity, e.g., ECG. The undersensing may be due to very small signal amplitudes or due to a sudden increase in single peak amplitude resulting in an increased sensing threshold. The undersensing may result in falsely detecting a cardiac event, e.g., asystole or bradycardia. The techniques of this disclosure monitor the behavior of the signal to determine when a detected asystole is false.
