Key result
Transesophageal low-energy cardioversion terminates 100% of provoked VF or flutter episodes.
Why the study?
The feasibility and efficacy of terminating life-threatening ventricular tachyarrhythmias by low-energy transesophageal shocks had not been established.
Does transesophageal low-energy cardioversion terminate life-threatening ventricular tachyarrhythmias in an animal model?
Comparison
Low-energy synchronous or asynchronous transesophageal shocks

Transesophageal cardioversion terminates VF in animal models; leaves open translation to human ventricular tachyarrhythmia management.
Does transesophageal low-energy cardioversion terminate life-threatening ventricular tachyarrhythmias in an animal model?
Transesophageal low-energy cardioversion is feasible and effective for terminating ventricular tachyarrhythmias in a healthy dog and pig model.
Cai et al. (1989) studied Life-threatening ventricular tachyarrhythmia (n=14). Transesophageal low-energy cardioversion was evaluated on Termination of ventricular fibrillation or flutter. Transesophageal low-energy cardioversion successfully terminated all 43 provoked episodes of ventricular fibrillation or flutter with a mean defibrillation energy threshold of 23.11 +/- 6.28 J.
