Intracardiac cardioverter defibrillators (ICDs) are expected to detect and to treat ventricular arrhythmias (VAs) in patients with previously documented VAs (secondary indication) or in patients at high risk of occurrence of VAs (primary indication).1,2 The treatment process includes the detection of VAs followed by the delivery of a therapy, i.e. antitachycardia pacing (ATP) and/or shocks. One of the main challenge of the devices is to detect the arrhythmia correctly, including noise rejection, and to identify its origin, i.e. supraventricular or ventricular, and thus to deliver therapy or not. The technical objective is to deliver only appropriate therapy and to avoid inappropriate therapies especially shocks (high specificity), but without the risk of underdetection of a life-threatening arrhythmia (high sensitivity).1,2 The detection and classification of VAs are essentially based on two additional parameters: the ventricular rate and the number of intervals reaching this threshold needed to be detected [number of intervals to . . .
