Limitations of the algorithm to reconfirm ventricular fibrillation in a third-generation implantable cardioverter defibrillator

We report on inadequate shocks delivered by an ICD for VT converting spontaneously to AF with slow ventricular response. This represents a correct behavior of the reconfirmation algorithm, as the detection of intervals longer than the fibrillation detection interval and shorter than the bradycardia...

Description
Summary:We report on inadequate shocks delivered by an ICD for VT converting spontaneously to AF with slow ventricular response. This represents a correct behavior of the reconfirmation algorithm, as the detection of intervals longer than the fibrillation detection interval and shorter than the bradycardia escape interval is required to inhibit the shock.
