Why the study?
Does 150-J biphasic truncated exponential shock provide equivalent first-shock defibrillation efficacy compared to 200-J monophasic damped sine shock in patients with electrically-induced ventricular arrhythmias?

Does 150-J biphasic truncated exponential shock provide equivalent first-shock defibrillation efficacy compared to 200-J monophasic damped sine shock in patients with electrically-induced ventricular arrhythmias?
150-J biphasic truncated exponential shocks provide highly effective defibrillation for electrically-induced VF, equivalent to 200-J monophasic shocks but with significantly lower peak current.

Higgins et al. (2004) conducted a cohort in Electrically-induced ventricular fibrillation or ventricular tachycardia (n=96). 150-joule impedance-compensated biphasic truncated exponential (BTE) shocks vs. 200-J monophasic damped sine (MDS) shocks (historical control) was evaluated on First-shock success rate for ventricular fibrillation (p=0.001 for equivalence).
