[Evaluation of the early signs of left ventricular failure using bipolar chest rheography].
The comparison of findings obtained with bipolar chest rheography with radiologic evidence of hypervolemia in the pulmonary circulation and left-ventricular end-diastolic pressure in 90 coronary patients has suggested that the basal impedance index (the ratio of estimated to actual basal impedance values) can be measured as it corresponds to the severity of pulmonary congestion. The basal impedance index values below 6.10(-2) signal congestive left-ventricular failure.
