Arterial pulse wave measurement system and pulse wave measurement method

An arterial pulse wave measurement system and a pulse wave measurement method are provided. The system includes a first sensor, a pressurizing element, and a processing device. The first sensor is arranged on the radial artery to detect a pulse wave amplitude of a radial artery. The pressurizing element contacts the first sensor to pressurize the first sensor. The processing device is coupled to the first sensor and the pressurizing element so as to control the first sensor to continuously detect the pulse wave amplitude and control the pressurizing element to continuously pressurize. When the processing device confirms that the pulse wave amplitude starts to decrease, the processing device controls the pressurizing element to depressurize until the pulse wave amplitude returns to a maximum amplitude pulse wave and records the pulse wave waveform of the radial artery under a constant pressure.
