The electrocardiographic behavior of the heart was observed in 100 patients undergoing heart operations. Most of the arrhythmias were unrelated to the cardiac operative procedure, but as in other thoracic procedures, were related to hypoxia, level of anesthesia, vagal reflexes, and changes in blood pressure. T_A and S-T displacements occurred in all groups and were thought to be related to altered dynamics of the right auricle and ventricle. Prevention, recognition and control of disturbances of cardiac mechanism are discussed.
