Exercise, isoproterenol infusion, and electrical pacing have been utilized in the assessment of the myocardium in patients with coronary artery disease. The electrocardiographic (ECG) and metabolic effects of tachycardia induced by pacing from the anterolateral position in the coronary sinus were analyzed in 5 normals and 10 subjects with cineangiographically proved anterolateral coronary artery disease of greater than 50% narrowing. All 15 subjects were in normal sinus rhythm, and none had A-V or intraventricular conduction defects.
Mean control heart rate was 73 and rose to 113 per minute during coronary sinus pacing. Control P-R interval ranged from 0.12 to 0.20
