Key result
ICD recovers VT sensing at 6 weeks following initial postoperative failure.
Why the study?
Failure to sense ventricular tachycardia or ventricular fibrillation is an important clinical problem associated with the use of the automatic implantable cardioverter-defibrillator.
Population
Single patient with AICD after open-heart surgery
Comparison
Failure to sense VT early after implantation vs subsequent sensing at 6 weeks
Design
Case report
Follow-up
6 weeks

Postoperative AICD undersensing may resolve spontaneously; single-case observation leaves open mechanisms and monitoring protocols.
Case Report (n=1)
Glicksman et al. (1988) conducted a case report in Ventricular tachycardia and automatic implantable cardioverter-defibrillator implantation (n=1). Automatic implantable cardioverter-defibrillator (AICD) was evaluated on Sensing of ventricular tachycardia. An automatic implantable cardioverter-defibrillator that initially failed to sense ventricular tachycardia following open-heart surgery successfully sensed it 6 weeks later in a single patient.
