Impedance rheographic-cardiography has been performed in 40 patients with chronic congestive heart failure. At the same time, polycardiographic data have been recorded and used for the correlative analysis. A curve dZ/dt has been analysed and "S", "X", "A", "O" waves amplitudes together with A/S and X/S ratios have been calculated, depending on the degree of heart failure.

One hundred and four coronary patients (the average age was 54 years), underwent treadmill testing. Hypotension during exercise testing was defined as a fall in systolic blood pressure for 10 mmHg or more, below the peak value in effort.
