METHOD FOR DETERMINING THE AREA PORT HUMAN HEART VALVE by measuring the stroke volume, heart rate and the average linear blood flow through the valve

摘要

A method for determining the area of ​​the heart valve orifice, characterized in that, in order to simplify the process and increase its accuracy, measured stroke volume, heart rate and average linear flow rate through the valve and the valve opening area is determined by the formula! Skl = (UO · CHCC) / 15 · Vcp.
