Alternating pulse is a pathological phenomenon in which the pulse rhythm is normal and the strength of the pulse alternates, and is evident in the sitting position. It is associated with alternating strength of ventricular contraction and is often indicative of left heart insufficiency. The occurrence of alternating pulses is associated with alternating strength of left ventricular contraction, suggesting myocardial injury and failure, and is strong evidence of occult heart failure. Some people suggest that the weak beat is caused by a decrease in the number of myocardial fibers participating in ventricular contraction, when part of the heart is in a relative non-response period, and in the next beat, all myocardial fibers contract, thus producing a strong pulse. Others have proposed the explanation of unequal ventricular diastole, and believe that when the heart is filled with more blood volume, its beat is enhanced, and vice versa is weak, and when the strength and weakness alternate, the pulse is alternate. When the venous filling pressure is reduced, the alternating pulse is more obvious, and vice versa, so the alternating pulse is often found in the obvious right-sided stasis heart. Micro pulse: the pulse is extremely thin and soft, and when pressed, it seems to be absent. Yang is weak and weak, unable to agitate, so see micro pulse. A kind of pulse. It is extremely thin and soft, and when it is pressed, it seems to die out, if there is any, to the point where the number is unknown. It is caused by a deficiency of qi and blood. Most often seen in shock? Deficiency? Chronic weakness disease, etc. Substitute pulse: A pulse that comes slowly and with regular intervals, and with long intervals. The substitution pulse is mainly related to the weakening of the vital energy, wind evidence, pain evidence, panic, and bruises. The decay of the organ qi, loss of qi and blood, and lack of vital energy cause the pulse to fail to connect and appear as a substitute pulse. It can also be caused by wind, pain, panic, and bruises, resulting in intermittent pulse. Substitute pulses can also be seen in women with abnormal physique or pregnancy, but the pulse is strong, soft and even, and should not be considered as a sick pulse. When the pain is severe or when a person is frightened, the pulse may appear temporarily due to Qi and blood rebellion, which is a temporary phenomenon different from the pulse of the weakening of dirty Qi. The substitute pulse originates from premature heartbeat or atrioventricular block, and is seen in various organic heart diseases. Counting pulse: The pulse comes rapidly, with five or more breaths in one breath. Pulse Classic: “Numbered pulses come and go rapidly.” Numerous pulses are mainly heat evidence. Because the evil heat agitation, blood flow accelerates, the pulse number and strong for the actual heat within the Sheng; if the long-standing disease Yin deficiency, deficiency heat within the growth, blood flow accelerates, the pulse number and weak, for the deficiency heat evidence. Deficiency pulse: the pulse that feels weak when lifting and pressing the three parts of the inch and the foot. It is a general term for weak pulse. The deficiency pulse is the main deficiency evidence, mostly due to deficiency of qi and blood or deficiency of internal organs. Insufficient qi and blood, qi is not enough to implement the blood vessels, then the pulse comes weak; blood is not enough to fill the pulse, so the pulse is empty when pressed. Deficient function of the internal organs, loss of essence, blood and fluid, that is, various chronic wasting diseases, often visible deficiency pulse. The deficient pulse is even more significant when the deficient blood is difficult to fill the pulse due to high fever and Yin injury, water loss, bleeding, or insufficient fluid after vomiting and diarrhea. String pulse: refers to the pulse with bowstring sensation, lifting the hand and pressing it does not turn, the long end of the string is straight like a silk string, how to recognize the lightness of the disease, the finger on the string soft and hard to see. The string pulse is the main pulse of liver and gallbladder disease, liver is rigid organs, disease is the meridian tendon meridian emergency, so the end of the pulse is straight and string. Pain evidence pulse also more string image, because the stomach and abdominal pain is mostly due to liver qi cross rebellious grasping spleen earth. In addition, the pain is mostly caused by cold, which is the main attraction, making the meridians tense and urgent, so the pulse is string. The phlegm drink stays in the two ribs where the liver meridian passes, called hanging drink, and also appears as a string pulse. Modern patients with arteriosclerosis are typical of the string pulse. Slippery pulse: slippery pulse is the pulse to fluent, should mean round and slippery, such as pearls walking plate, rolling slippery. The slippery pulse is the main phlegm, phlegm drink. Because the phlegm drink is internally blocked, in the case of positive qi is not deficient, can appear qi and blood surge, so the pulse shows slippery. In a patient with high fever, the pulse is also slippery when the heat is encouraged to move the blood, and in a woman after conception, the qi and blood gush to feed the fetus, so the typical slippery pulse is even more visible.
