Key result
EPS-guided sotalol therapy significantly reduced VTA recurrence in responding patients (13%) compared to nonresponders (63%) and ICD-only recipients (46%).
Why the study?
Does EPS-guided sotalol combined with ICD reduce VTA recurrence in patients with structural heart disease and sustained VTA?
Cohort (n=92)
Does EPS-guided sotalol combined with ICD reduce VTA recurrence in patients with structural heart disease and sustained VTA?
Absolute Event Rate: 30% vs 46%
EPS-guided sotalol therapy combined with an ICD significantly reduces VTA recurrence and inappropriate ICD discharges in patients who are EPS responders.

May support EPS-guided sotalol in responders; hypothesis-generating and requires randomized confirmation before practice change.
Watanabe et al. (2005) conducted a cohort in Ventricular tachyarrhythmias (VTA) and structural heart disease (n=92). Electrophysiologic study (EPS)-guided sotalol administration combined with ICD vs. ICD-only (untreated with antiarrhythmic drugs) was evaluated on Recurrence of VTA. EPS-guided sotalol therapy significantly reduced VTA recurrence in responding patients (13%) compared to nonresponders (63%) and ICD-only recipients (46%).
