Fast and weak pulse

Introduction Pulse fast is the pulse rate is greater than four quarters, weak pulse is a modern word, is a proper noun, refers to the pulse of the soft and sinking, weak and slippery pulse. Weak veins are more common in deficiency syndrome of qi and blood deficiency. If the blood deficiency is not filled, the pulse is fine; if the pulse is weak, the pulse is weak and weak. When inhaling, the pulse is significantly weakened or even disappeared, which is called odd pulse. Qimai is one of the important signs of pericardial tamponade, mainly due to the decrease in left ventricular stroke volume. When the pericardial tamponade, the increase in the negative pressure of the chest during inspiration increases the blood volume of the pulmonary circulation, but due to the limited diastolic, the reflux of the systemic circulation to the right ventricle cannot be increased accordingly.

Cause

The weak pulse is due to insufficient heart swell, mainly because the heart muscle is not strong enough, the body is weak, the small heart and so on. Because the heart is a "blood pump", the heart is not fully powered, and the natural blood supply is insufficient. It is as if the water pressure is not enough, and it is easy to stop the water in a higher place. Not excluding the lack of blood, it is a manifestation of weakness. The causes of tachycardia vary widely. The most common is the heart itself, such as various types of heart disease, myocarditis, heart failure and so on. Suffering from systemic diseases such as anemia, fever, acute and chronic infection, shock, hyperthyroidism, gas poisoning, can also cause tachycardia. When a normal person is exercising or agitated, serving spirits, strong tea, espresso or more smoking, and taking certain drugs can accelerate the heart.

Pulse: index finger, middle finger, ring finger at the same time gently press the wrist and iliac artery, normal human pulse beats the rules and powerful, in a calm state, men's pulse beat 60-80 beats per minute, women's pulse beat 70-90 beats per minute, newborn Pulse beats up to 130 beats per minute. If the pulse is too fast or too slow, irregular or undetectable, you should ask your doctor for further diagnosis.

Differential diagnosis

1. Anemia: Anemia can lead to fatigue, low fever, weak body, accelerated pulse, dizziness, pale nails, lips and eyelids, irritability or depression, drowsiness, mouth pain, and women's menopause. The initial symptoms of slowly forming anemia include loss of appetite, headache, constipation, irritability, and difficulty concentrating. It usually results from acute or chronic blood loss or insufficient erythropoiesis, such as iron deficiency, vitamin B12, folic acid and protein, drugs, hormonal lesions, surgery, pathogens, stomach ulcers, hemorrhoids, diverticulosis, excessive menstrual bleeding, multiple pregnancies Liver damage, thyroid disease, rheumatoid arthritis, bone marrow disease, radiation exposure and dietary deficiencies are all possible causes of anemia; bone marrow hematopoietic dysfunction (such as aplastic anemia), excessive red blood cell destruction is also caused One of the causes of anemia.

2, infection: medical history and symptoms can provide important clues for unexplained fever, travel, contact with certain items or animals and other information is also very important. For example, in some areas of the United States, there is a local endemic area of coccidioidomycosis and histoplasmosis. Typhoid fever may have a history of drinking unclean water, and brucellosis may have a history of working in a meat processing plant.

In the case of fever for unknown reasons, the heat type generally has no diagnostic value, but there are exceptions. A fever every other day or a fever every 3 days suggests malaria, but it is still necessary to find the malaria parasite from the blood smear. In the case of periodic neutropenia, the number of neutrophils decreased to a very low level every 21 days, often causing infection and fever. For patients with periodic fever, Hodgkin's disease should be suspected. A comprehensive and repeated physical examination, especially skin, eyes, nail bed, lymph nodes, heart, abdomen, etc. is very important.

3, hyperthyroidism: clinically a very common endocrine disease. Refers to a multi-system of the nervous system, circulatory system, digestive system, cardiovascular system, etc. caused by various reasons such as increased thyroid function, excessive secretion of thyroid hormone or increased levels of thyroid hormones (T3, T4) in the blood. A series of high metabolic syndrome and high excitatory and ocular symptoms.

Pain, tachycardia, heat, sweating, appetite, weight loss, weight loss, fatigue, weakness, emotional excitement, impatience, insomnia, insufficiency, eyeballs, trembling, goiter or swelling, female There may be menstrual disorders or even amenorrhea, men may have impotence or breast development. The thyroid enlargement is symmetrical, and some patients have asymmetrical enlargement. The goiter or swollen assembly moves up and down with swallowing, and some hyperthyroidism patients have thyroid nodules.
