METHOD FOR MEASURING PULSE WAVE PROPAGATION SPEED IN CEREBRAL ARTERIES Russian patent published in 2006 - IPC A61B8/06 A61B5/02 

FIELD: medicine.

SUBSTANCE: method involves synchronously recording electrocardiogram in standard lead and pulse wave dopplerogram taken from M1 segment of medial cerebral artery using transducer of 1.7-2.5 MHz frequency and scanning speed of 50-100 mm/s. Delay time of rise onset is determined on dopplerogram relative to S-tooth peak or descending R-peak slope end on electrocardiogram. Pulse wave propagation speed on aorta-M1-segment part of the medial cerebral artery is calculated in cm/s from formula V=0.93*(S₁+S₂)/t, where 0.93 is the coefficient of measurement error on body surface of length of aorta-M1-segment of medial cerebral artery, S₁ is the distance from sternal jugular fossa to mandible angle, S₂ is the distance from mandible angle to point of intersection of the anterior auricle edge and upper edge of zygomatic arch in cm, t is the delay time in s.

EFFECT: wide range of functional applications.
