When the pulse beats more than 100 times and is pressed like a thin line, it is called a fine pulse. Fine pulse is mainly caused by tachycardia, fine is the concept in Chinese medicine, fine pulse main qi and blood deficiency, all deficiencies and labor losses. Due to various diseases and qi deficiency is unable to push the blood to run, blood deficiency can not fill the pulse channel, the pulse body is small and weak. The dampness of the pulse can also be seen when it is blocked by dampness. Before counting the pulse, let the patient rest quietly for a while to avoid activity and excessive excitement, which can affect the accuracy of the pulse. When counting the pulse, not only to determine the number of times per minute, but also pay attention to the rhythm, elasticity and strength of the pulse. Normal people have a strong and elastic pulse, which can be easily felt on the flexural artery beating on the outside of the palm surface of the wrist. In adults, if the number of pulses per minute is more than 100, and when pressed like a thin line, it can be diagnosed as a fine pulse rate. Auxiliary examination of pulse rate: 1, pulse strength examination Pulse strength examination is an auxiliary examination method used to check whether the pulse rate is normal. The strength of the pulse is related to the volume of the heart beat, pulse pressure and peripheral vascular resistance. An increased pulse with high amplitude is due to a high volume of heart beats, wide pulse pressure and low peripheral resistance, and is seen in hyperthermia, hyperthyroidism, and aortic valve insufficiency. A weakened pulse with low amplitude is due to a low pulse volume, low pulse pressure and high peripheral resistance, and is seen in heart failure, aortic stenosis and shock. This test can determine the location of the lesion and the corresponding signs. 2.Pulse wave velocity Pulse wave velocity is an ancillary test used to check whether the arterial vasculature is normal. Arterial stiffness has been recognized as an independent risk factor for cardiovascular disease and can independently predict hypertension, coronary artery disease, diabetes, end-stage vascular nephropathy, cardiovascular disease in natural populations and all-cause mortality and death, and is associated with left ventricular hypertrophy, stroke and dementia, so detection of atherosclerosis has important clinical significance. The clinical significance of non-invasive atherosclerosis testing for the evaluation of early vascular lesions is gaining attention, with carotid-femoral pulse wave velocity being the “gold standard” for detecting atherosclerosis. Realistic and reliable measurements ensure the accuracy and credibility of the research results. This test can be used to determine the corresponding signs of disease.
