Title:
DEVICE FOR DETECTING START POINT OF ARTERIAL PRESSURE RISE TO CALCULATE MECHANICAL INTERVAL THEREOF
Document Type and Number:
Japanese Patent JPS5239984
Kind Code:
A
Abstract:
Apparatus and a method for determining the onset of an interarterial blood pressure pulse and measuring the time delay preceding the onset from the corresponding electrical heartbeart triggering signal wherein the blood pressure pulse is converted to an electrical input signal which is split into two identical components, one being delayed in time, inverted and amplified after which it is added to the other. A timer measures the duration between the electrical heartbeat actuating signal and the point at which the sum of the blood pressure component signals reaches a peak and subtracts from that result the time delay applied to the one component to yield the electromechanical interval between the electrical heartbeat signal and onset of the blood pressure pulse.
