Coronary hypertonia and angina.
Coronary hypertonia was observed in a patient with unstable angina. It was possible on one occasion to reproduce the clinical picture, electrocardiographic changes, lactate production and coronary hypertonia by means of atrial pacing. He had a normal left coronary arteriogram when the diffuse spasm was relieved by nitroglycerin. Therefore hypertonia (or spasm) of the left coronary artery was believed to be the cause of his variant angina with subendocardial ischemia.
