SVT may trigger noise reversion mimicking DDD pacemaker malfunction; single case extends sensing mechanism insights but leaves open prospective validation.
Case Report (n=1)
Supraventricular tachycardia can trigger noise reversion mode in DDD pacemakers, leading to asynchronous pacing that mimics pacemaker malfunction.
Fontaine et al. (1988) conducted a case report in Supraventricular tachycardia in a patient with a DDD pacemaker (n=1). DDD pacemaker was evaluated on Asynchronous dual chamber or noise reversion pacing. Supraventricular tachycardia at 215 bpm in a patient with a DDD pacemaker triggered asynchronous dual chamber pacing due to QRS complexes falling into the noise sampling period.
