A substrate-based strategy was used in 338 cases (87%), and a strategy of targeting premature ventricular complex (PVCs)\/ventricular tachycardias (VTs) that triggered ventricular fibrillation (VF) in 47 cases (12%), with combined abnormal electrogram and PVC\/VT ablation in 3 cases (1%). Sodium channel blocker was frequently used to augment the arrhythmogenic substrate in 309\/388 cases (80%), which included a variety of agents, of which ajmaline was most commonly used. After ablation procedure, the pooled incidence of non-inducibility of VA was 87.1% (95% confidence interval [CI], 73.4\u201394.3; <jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u200951%), and acute resolution of type I ECG was seen in 74.5% (95% CI [52.3\u201388.6]; <jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u200975%).
