Selective coronarography, assessment of hemodynamics, sinus node function, sinoatrial and intraatrial conduction were performed in 53 coronary heart disease (CHD) patients with supraventricular arrhythmia. The severity of cardiac rhythm paroxysms was evaluated at transesophageal pacing by measurements of arrhythmia induction frequency threshold. 29 patients underwent aortocoronary shunting. No relationships were found between the pattern of arrhythmia, degree of stenosis, number of coronary lesions. Aortocoronary bypass changed neither pattern nor severity of supraventricular arrhythmia.
