BIVentricular versus right ventricular antitachycardia pacing to terminate ventricular tachyarrhythmias in patients receiving cardiac resynchronization therapy: The ADVANCE CRT-D Trial

Influence of cycle length variations on antitachycardia pacing effectiveness among ICD patients

“…8 In this sense, it has been shown that ATP from the right ventricular apex is less effective for VTs with basal exit 9 and that biventricular pacing (compared with right ventricular pacing) is more effective in ischemic patients. 10 However, to the best to our knowledge, no other stored electrogram-based variables have been studied in order to establish their relationship with the effectiveness of ATP. Because CL variability is common in VT occurring spontaneously in ICD patients, 11 we conducted a prospective study aimed at determining the relationship between both the degree and the pattern of variation of VT CL and the efficiency of the subsequent ATP.…”

Antitachycardia pacing for reduction of implantable cardioverter-defibrillator shocks

“…23 Analysis of the ADVANCE CRT trial also seemed to suggest a benefit from biventricular ATP delivered to patients with ischemic scar substrate (ie, coronary artery disease) presumably related to left ventricular stimulation closer to the circuit. 24 However, another analysis demonstrates that pace induction and termination of VT is adaptable across different pacing sites. 25 In general, faster VTs have a shorter excitable gap that is more difficult for the pacing stimulus enter but not necessarily to terminate once penetrated.…”

Efficacy of Anti-Tachycardia Pacing for Terminating Fast Ventricular Tachycardia in Japanese Implantable Cardioverter Defibrillator Patients

“…17- 20 The etiology of VT in those studies, however, was predominantly for overdispersion. To evaluate the effects of background factor on ATP efficacy, the odds ratios adjusted for within-patient correlation were estimated on univariate and multivariate logistic regression.…”
