A diagnostic device for measuring pulse waves from an upper arm is provided. The device includes a cuff, a sensor, and a processing circuit. The cuff provides continuously a pressure to arteries of the upper arm. Then the sensor measures a plurality of pulse waves from an upper arm in response to the pressure. The plurality of pulse waves includes a single pulse wave. The processing circuit, coupled to the sensor, generates data of the plurality of pulse waves. According to data of the single pulse wave extracted from the data of the plurality of pulse waves, the processing circuit computes and outputs diagnostic data.
