A New Algorithm to Reduce Inappropriate Therapy in the S-ICD System

The subcutaneous ICD system (S‐ICD) has been shown to be a safe and effective treatment for patients at risk for sudden cardiac death. This device reliably detects ventricular tachyarrhythmias with a low incidence of inappropriate shocks for supraventricular arrhythmias. However, T‐wave oversensing (TWOS) is more common with the S‐ICD compared with transvenous systems. We developed a novel discrimination algorithm to reduce TWOS without compromising tachyarrhythmia discrimination.
