title: [ECG changes during an attack of stenocardia caused by physical exertion].
abstract: In 85 patients suffering from ischemic heart disease ECG changes appearing at the time of an attack of angina pectoris provoked by a physical effort were studied. An analysis of these changes helps substantiate an objective choice of criteria for stopping a physical load test in this category of patients. As shown by pertinent investigations there is good reason for broadening the criteria for cancelling the load test in persons with a manifest coronary incompetence. A complete scientific justification of criteria for cancelling tests involving physical efforts is possible through contrasting the described changes against coronarographic, clinical and catamnestic findings.
