organs pulse and the four-seasons pulse are important components of pulse diagnosis in

Huangdi Neijing

， with the heart vessel pulse being a key part. According to the

Pulse Classic

（

Maijing

）， it is located at the "left inch" position， that is， within one inch between the radial tuberosity of the left wrist and the thenar eminence along the radial artery. Later physicians largely based their pulse-taking methods on this position. In terms of pulse characteristics， a "hooked" heart vessel pulse is considered normal， whereas excess or deficiency indicates pathology， reflecting the state of exuberance and decline of
