Now in the clinic many women come to see the doctor like to let the doctor feel the pulse to determine whether the pregnancy, generally we still advocate the four diagnostics together, if necessary, but also combined with Western medicine examination. We all know that the pulse before menstruation may also appear slippery, nearly two months after pregnancy when the pulse is slippery the most obvious, and some obese people usually pulse is manifested as slippery pulse. Therefore, we can not rely on a slippery pulse alone to determine whether or not you are pregnant. Slippery pulse is one of the pulse signs in TCM pulse diagnosis. 1, pulse check is used to check whether the pulse is normal an auxiliary inspection method. Pulse refers to the beating of the arteries. The pressure change caused by the heart beat makes the wall of the aorta vibrate, which is transmitted to the periphery along the arterial wall, i.e. pulse. The pulse is often referred to as the pulse felt on the radial side of the wrist. The pulse can also be recorded with a pulse meter. The pulse reflects the functional status of the circulatory system. The content of the pulse examination includes examination of the rate, rhythm, tension, strength, waveform, and condition of the arterial wall. This test is used to determine the location of the lesion and the corresponding signs of disease. The pulse is examined by palpation, but a bedside monitor can also be used to continuously display and record the pulse, and to directly observe changes in pulse waveform, rhythm, and frequency. When checking the pulse, a superficial artery must be selected, and the radial artery is usually used. Under special circumstances, the temporal artery, carotid artery, brachial artery, femoral artery and dorsalis pedis artery can also be checked. The examiner’s fingers are put together, and the fingers of the index, middle and ring fingers are placed flat on the radial artery near the wrist, and the pulse is carefully felt. Both sides should be palpated for comparison. In normal people, the difference between the two sides is so small that it is difficult to detect. In some diseases, there is a marked difference between the two sides of the pulse. The pulse may be unequal in strength or absent on one side. The pulse of the upper and lower extremities should be examined for comparison, and blood pressure measurements of the upper and lower extremities should be taken at the same time. To detect certain diseases. Such as multiple aortitis, aortic constriction. 2. Pulse wave velocity is an auxiliary 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 heart disease, diabetes, end-vascular nephropathy, cardiovascular disease in natural populations, and all-cause mortality and mortality, and is associated with left ventricular hypertrophy, stroke, and Alzheimer’s disease, etc. Therefore, the detection of arteriosclerosis is of great clinical significance. The clinical significance of non-invasive atherosclerosis testing in evaluating early vascular disease has been increasingly emphasized, with carotid-femoral PWV being the “gold standard” for atherosclerosis detection. Real and reliable measurements ensure the accuracy and credibility of the research results. The test can determine the corresponding signs of disease. The examinee takes the supine position, puts the pressure receptor on the right side of the carotid artery, the femoral artery, the radial artery fluctuates the most obvious part, measures the surface distance between these two points and inputs it into the computer, the pwv is calculated according to the distance between the two pulse waves than the time of the pulse wave conduction.
