title: [Measurement of the electrical impedance of the chest cavity under physical load for the detection of left ventricular insufficiency in ischemic heart disease].
abstract: The suggested index of transthoracic impedance time course during loading (20 and 50 V) correlates significantly with the complex index of phase analysis (ratio of the duration of the tension and ejection periods), the stroke and cardiac indices and the QAd index determined by rheography and, at the same time, it is more informative. Its highly significant connection with tolerance to physical load is also noted.
