[Changes in arterial pressure, heart contraction rate and ECG indices in ischemic heart disease patients undergoing...

Thirty males with coronary heart disease were examined using bicycle ergometry and a combined statico-dynamic test. It was established that the latter was accompanied by a more rapid (as compared with bicycle ergometry) increase of the heart rate, the systolic arterial pressure, the value of "double multiplication" and, in contrast to dynamic exercise, by an elevation of the diastolic arterial pressure. During a combined test an anginal attack and displacement of the ST segment occurred earlier as against bicycle ergometry. The above characteristics of the hemodynamics during the statico-dynamic exercise justify the use of this test for studying the relationship of the coronary blood flow and myocardial contraction.
