Epicardial electrogram of the right ventricular outflow tract in patients with the Brugada syndrome: using the epicardial lead.
We tried to record an epicardial electrogram directly, and we examined local electrograms before and after administration of a class IC anti-arrhythmic drug in patients with the Brugada syndrome. ⋯ An epicardial electrogram can be recorded from the CB. Recording from the CB enables identification of an epicardial abnormality in patients with the Brugada syndrome. These abnormal electrograms may be related to a myocardial abnormality in the epicardium of patients with the Brugada syndrome.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialBiphasic versus monophasic shock waveform for conversion of atrial fibrillation: the results of an international randomized, double-blind multicenter trial.
This study compared a biphasic waveform with a conventional monophasic waveform for cardioversion of atrial fibrillation (AF). ⋯ For the cardioversion of AF, a biphasic shock waveform has greater efficacy, requires fewer shocks and lower delivered energy, and results in less dermal injury than a monophasic shock waveform.
