Why the study?

Does an antitachycardia pacemaker and ICD combination safely and effectively terminate VT in highly selected patients with recurrent hemodynamically stable VT?

Key Points

To evaluate the long-term efficacy of combining antitachycardia pacemakers with implantable cardioverter defibrillators in treating ventricular tachycardia.
Implanted antitachycardia pacemakers and ICDs in 14 patients after comprehensive electrophysiology testing.
Utilized burst scanning mode for antitachycardia pacing during the procedure.
Followed patients for a mean of 25 months to monitor episodes of ventricular tachycardia.
A total of 6,029 episodes of ventricular tachycardia were treated with only 103 ICD discharges required (1 discharge per 60 VT episodes).
Ten out of 14 patients received discharges from their ICDs during the follow-up period.
No patient deaths occurred, and all devices remained active in the automatic mode.

Structured PICO

Does an antitachycardia pacemaker and ICD combination safely and effectively terminate VT in highly selected patients with recurrent hemodynamically stable VT?

Population

14 patients with recurrent hemodynamically stable ventricular tachycardia (VT) who underwent extensive preimplant testing documenting that at least 50 episodes of VT could be reliably terminated by an external model of the antitachycardia pacemaker.

Intervention

Antitachycardia pacemaker (burst scanning mode) and implantable cardioverter defibrillator (ICD) combination, with ICD implanted solely as a backup with high nonprogrammable rate cutoffs (mean 191 ± 12 beats/min).

Outcome

Efficacy in terminating VT episodes and requirement of ICD discharges

An antitachycardia pacemaker and ICD combination can safely and effectively terminate VT with rare need for ICD discharges in highly selected patients.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May reduce shocks with ATP-ICD in select stable VT; leaves open broader efficacy without prospective trials.
