Baseline characteristics of the study patients
The baseline characteristics of the study participants are listed in
Table 1. The prevalence of CRT-D implantation was significantly higher
in the RR-NSVT (-) group (55.9% vs. 32.4%; p=0.009). More frequent use
of amiodarone (57.4% vs. 36.8%; p=0.025) and less frequent use of
angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker
(75.0% vs. 89.7%; p=0.041) was noted in the RR-NSVT (-) group.
