ELECTROCARDIOGRAPHIC STUDIES DURING ATTACKS OF ANGINA PECTORIS AND OF OTHER PAROXYSMAL PAIN

Abstract

study obtained similar curves from ligature of the ramus descendens of the left coronary artery. These changes were most pronounced after further ischemia of the heart muscle was produced by obstruction of the inferior vena cava. These clinical and experimental data are strong evidence that myocardial ischemia is responsible for the changes in the T wave and S-T segment of the curves. Likewise, they indicate that the pain is probably due to or associated with myocardial ischemia.
