Peripheral vascular signs mainly include capillary pulsation sign, obvious carotid artery pulsation, gunshot sound, nodding movement and double murmur of these five, but the pulse pressure increases can appear capillary pulsation, the examination method is to press the patient’s fingernail end to observe whether there is a red-white alternating phenomenon, the carotid artery pulsation under the state of quiet is abnormal, mainly because of the increase in pulse pressure. In the arteries of the limbs, a short systolic sound like the sound of a gunshot is called a gunshot sound, and when the stethoscope is placed on the femoral artery and a little force is exerted, a murmur can be heard during systole and diastole, which can appear in a blowing wind-like manner. The patient takes a sitting position, due to the increase of pulse pressure, the head blood vessel pulsation enhancement, the patient appeared every time the heart bo head up and down bobbing signs, known as nodding movement, mainly related to the increase of pulse pressure. Through the examination of different parts of the body, the site of the lesion and the corresponding disease can be determined.
