| Description: |
Retrograde Conduction During Inducible Sustained Monomorphic Ventricular Tachycardia in 305 Implantable Cardioverter Defibrillator Recipients. Despite the advent of dual chamber ICDs, differentiation of VT (SMVT) with 1:1 VA conduction will remain a challenge. In this study, VA conduction capability and prevalence of inducible sustained monomorphic (SM) VT with 1:1 VA conduction was assessed in 305 ICD recipients. SMVT with a mean cycle length (CL) of 304 ± 61 ms was induced in 161 (53%) patients. Twenty‐six percent of the patients maintained 1:1 VA conduction to CL ≤ 400 ms during incremental ventricular pacing, regardless of presenting tachyarrhythmia or presence of inducible SMVT. Among ten patients who had inducible SMVT with possible 1:1 VA conduction (based on SMVT CL comparable to the shortest CL associated with 1:1 retrograde conduction during ventricular pacing), all seven with available intracardiac tracings had documented 1 :1 VA conduction during the induced SMVT—representing 4.4% of the patients with inducible SMVT (95% CI 1.2%‐7.6%), and 2.3% of the entire ICD cohort (95% CI 0.6%‐4.0%). We conclude that about one‐fifth of ICD recipients possess 1:1 VA conduction to CL ≤ 400 ms and that inducible SMVT with 1:1 VA conduction can be demonstrated in a small hut nonnegligible proportion of ICD recipients. These data are relevant to the design of tachyarrhythmia‐discrimination algorithms for dual chamber ICDs. |
