Implication

May support use in select refractory cases; hypothesis-generating and should not yet change practice.

Key Points

To evaluate the long-term clinical efficacy and potential limitations of permanent radiofrequency-triggered pacemakers in managing drug-refractory tachyarrhythmias.
Evaluated 7 patients receiving permanent radiofrequency-triggered pacemakers for recurrent paroxysmal supraventricular tachycardia (n=5), alternating bradycardia-tachycardia (n=1), or ventricular tachycardia (n=1).
Monitored clinical outcomes and arrhythmia control over a mean follow-up period of 36 ± 24 months.
Achieved successful long-term arrhythmia control in 5 of 7 patients, though 3 of these 5 individuals required concurrent antiarrhythmic medication.
Identified pacing failure in 2 of 7 patients: overdrive pacing failed in 1 patient with Wolff-Parkinson-White syndrome and recurrent atrial fibrillation/flutter, and 1 patient with ventricular tachycardia became refractory to overdrive pacing.

Does the insertion of permanent radiofrequency-triggered pacemakers improve arrhythmia control in patients with recurrent refractory arrhythmias?

Population

7 patients with recurrent paroxysmal supraventricular tachycardia (n=5), alternating bradycardia-tachycardia (n=1), or ventricular tachycardia (n=1)

Intervention

Insertion of permanent radiofrequency-triggered pacemakers

Outcome

Arrhythmia control at follow-up

Permanent radiofrequency-triggered pacemakers can provide long-term effectiveness in controlling recurrent refractory arrhythmias in carefully selected patients.
