FIELD: medicine.
SUBSTANCE: method involves performing cardiac cycle phase analysis using synchronously recorded electrocardiogram and aorta rheogram data obtained by continuously measuring contraction and expulsion period durations from two rheographic electrodes one of which is active and the other indifferent one, and following heart contraction force from the ratio of these time intervals. The indifferent electrode is arranged along the temporal and frontal bone boundary.
EFFECT: considerably reduced muscular noise interference.
