The recent introduction of direct-current external electric shock for the restoration of a normal sinus mechanism in patients with atrial fibrillation has reopened the question of the desirability of restoring a normal sinus pacemaker. To determine whether restoration of a sinus rhythm is hemodynamically beneficial to some or all patients, we have measured the cardiac output in a group of 47 patients with atrial fibrillation in whom an attempt at conversion was about to be made. The cardiac output determination was repeated if restoration of a normal sinus rhythm was accomplished.
All patients were given digitalis in doses sufficient to
