Suggests greater CO gain from conversion at higher rates; hypothesis-generating from single case report, needs prospective confirmation.
Does conversion to sinus rhythm improve cardiac output in patients with rapid arrhythmias?
Conversion to sinus rhythm from rapid arrhythmias immediately increases cardiac output, particularly when the pre-conversion heart rate exceeds 160 beats per minute.
Wright et al. (1970) studied this question.
