Abstract

Pulse wave velocity (PWV) is a basic parameter in the dynamics of pressure and flow wave traveling in arteries. But it is difficult to measure the pulse wave transmission time between coronary arterial proximal and distal point by manual method using the graph on which pulse wave and ECG are receded. The system that can measure PWV in real time was developed and clinical experiment was carried out for patients to validate the accuracy of the measured coronary arterial PWV. The average value of the measured coronary arterial PWV was 934.764plusmn104.606 cm/sec.
