Implication
Alerts clinicians to possible proarrhythmia from inappropriate ATP in ICDs; hypothesis-generating and should not change practice.

Structured PICO
P
Population
Two cases of patients with automatic cardioverter-defibrillators where supraventricular arrhythmias triggered device-mediated pacing therapy.
I
Intervention
Device-mediated pacing therapy triggered by supraventricular arrhythmias
O
Outcome
Induction of ventricular tachycardia requiring additional therapeutic interventionsafety
Automatic cardioverter-defibrillators may misdiagnose supraventricular arrhythmias and deliver inappropriate antitachycardia pacing, potentially inducing ventricular tachycardia.
Cite This Study
Johnson et al. (1991) conducted a case report in Supraventricular arrhythmias in patients with automatic cardioverter-defibrillators (n=2). Automatic cardioverter-defibrillators was evaluated on Induction of ventricular tachycardia requiring additional therapeutic intervention. Device-mediated pacing therapy from automatic cardioverter-defibrillators, triggered by supraventricular arrhythmias, induced ventricular tachycardia requiring additional intervention in two cases.
