Safety and efficacy of programming a high number of antitachycardia pacing attempts for fast ventricular tachycardia: a prospective study

Abstract

Programming a high number of ATP attempts (up to five ATP attempts) in the FVT zone is both safe and efficient and could prevent shocks in numerous ICD recipients.

Postmortem ICD interrogation in mode of death classification

“…We identified 163 citations of which 22 studies met the inclusion criteria (Figure and Table ) . The studies were undertaken between 1982 and 2015 with 23,600 participants.…”

ICD Follow‐Up and Troubleshooting

“…31,36 The incidence of syncope resulting from delayed therapy or VT acceleration does not appear to be significantly higher than shock-only programming. 23,35,42,43 Even in induced VT faster than 250 bpm, a 30% success rate was noted with up to six ATP sequences. 25,27 The success rate is higher if more sequences are used.…”

Atrioventricular Nodal Reentrant Tachycardia in Implantable Cardioverter Defibrillators: Diagnosis and Troubleshooting

“…The PainFREE Rx II trial showed that ATP in the Fast VT (FVT) zone (188–250 bpm) resulted in a significant reduction of shocks (28 vs. 64%) with low risk of acceleration or syncope . A single ATP sequence was used (8‐pulse burst pacing train at 88% of VT CL); however, another study suggested that up to 5 ATP attempts in the FVT zone (200–240 bpm) is both safe and efficient …”
