High-energy protocol preferred for transvenous VT cardioversion; confirms RCT superiority of higher energy for termination efficacy.
Does an incremental low-energy protocol compared to a high-energy protocol improve the efficacy and safety of transvenous cardioversion for termination of ventricular tachycardia in patients with organic heart disease?
Transvenous cardioversion for sustained VT has moderate efficacy that is higher with a high-energy protocol, but its use is limited by frequent acceleration of VT and transient arrhythmias.
Ciccone et al. (1985) studied this question.
