Randomized Controlled Trial Comparative Study Clinical Trial
Prospective, randomized comparison of two biphasic waveforms for the efficacy and safety of transthoracic biphasic cardioversion of atrial fibrillation.
The purpose of this study was to determine if there is a difference in commercially available biphasic waveforms. ⋯ Biphasic waveforms were very effective in transthoracic cardioversion of AF, and complication rates were low. No significant difference in efficacy was observed between BR and BTE waveforms. Impedance was not an important determinant of success for either biphasic waveform.
