Signals the device should not have counted: lead failure, electrocautery, T wave and myopotential oversensing.
The cases
1Oversensing of electrocautery2Surgical intervention and VF at the time of reperfusion3Inappropriate therapies during a TAVI procedure4Lead fracture and multiple capacitor charges5Oversensing of the P wave by the defibrillation lead6Oversensing of atrial activity by the defibrillation lead during an episode of atrial arrhythmia7Early displacement of a right ventricular lead into the atrium8T wave oversensing9Oversensing of diaphragmatic myopotentials
