capillary beat sign

The capillary pulsation check is an auxiliary test method for checking whether the blood vessel is normal. Use your finger to gently press the end of the patient's nail or gently press the lip mucosa of the patient with a slide to make the local whitish. When the heart contracts, the local redness will occur. When the heartbeat cycle occurs, the regular red and white alternating is the capillary pulsation. . (See the aortic valve severe regurgitation or peripheral capillary wall dilation) This test can determine the lesion and the corresponding symptoms. Basic Information Specialist classification: cardiovascular examination classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Reminder: During the examination, the patient actively cooperates with the doctor, and should not be overly stressed during the examination, so as not to affect the result. Normal value When normal, gently press the end of the patient's nail bed with a finger, or gently press the mucous membrane of the lips with a clean glass slide. There is no rhythmic microvascular pulsation alternating with red and white. Immediately after the pressure, the blood is filled. Clinical significance Abnormal results: Also known as "capillary pulsation phenomenon." Use your fingers to gently press the end of the patient's nail bed, or gently press the mucous membrane of the lips with a clean glass slide. If you see red and white alternating rhythmic microvascular pulsation, it is called capillary pulsation positive. Common in diseases with increased pulse pressure difference, such as patent ductus arteriosus, aortic insufficiency, hyperthyroidism and severe anemia. Regular physical examination items for people who need to be examined, abnormal blood vessels. High results may be diseases: aortic regurgitation, pregnancy with patent ductus arteriosus Forbidden before examination: Maintain a normal diet and schedule. Requirements for examination: The patient actively cooperates with the doctor during the examination, and should not be overly stressed during the examination, so as not to affect the result. Inspection process Use your fingers to gently press the end of the patient's nail bed, or use a clean glass to gently press the mucous membrane of the lips. For example, see the phenomenon of microvascular pulsation that is alternating between red and white and consistent with the patient's heart rhythm. It is caused by an increase in pulse pressure difference. One of the peripheral vascular signs of aortic regurgitation is also seen in patent ductus arteriosus, hyperthyroidism, severe anemia, and the like. Not suitable for the crowd Inappropriate people: severe blood vessels and heart failure.
