Bifocal demand pacing is indicated when a symptomatic sinus (or atrial) bradycardia occurs in patients having equally an intermittent atrioventricular block, when it is essential for the cardiac function that synchronism between atria and ventricles be perfect. 17 patients have been permanently paced. The electrodes where endocardial in 14 cases, and myocardial in 3 cases. Bifocal demand pacing favors the sequence of physiological depolarization without competing with intrinsic ventricular activity. A long term study, performed at present, seems to confirm the validity of this new mode of pacing.
