Applying Pulse Spectrum Analysis to Facilitate the Diagnosis of Coronary Artery Disease

Figure 1

(a) Landmarks of the pulse measurement position. The measurement positions are the surfaces of the radial arteries of both wrists. The white arrows indicate the styloid processes of the radius, the red cylinders represent the radial arteries, and the yellow dots represent the measurement position, i.e., the most prominent position of the pulsation at the wrist radial artery, which corresponds to the styloid process of the radius.

(b) Actual pulse measurement. The white arrow indicates the styloid process of the radius of left hand, and the yellow arrow indicates the measurement position.
