the hemodynamic effects of this procedure were evaluated by pacing at selected atrial sites postoperatively to simulate ( 1 ) sinus rhythm with a synchronous right atrial kick , ( 2 ) sinus rhythm without a synchronous right atrial kick , ( 3 ) right atrial tachycardia propagated to the entire heart ( propagated right atrial tachycardia ) , and ( 4 ) right atrial tachycardia confined to the isolated right atrium with sinus rhythm in the rest of the heart ( confined right atrial tachycardia ) .
