rapid pulse

Introduction

Introduction People of different ages have different pulse rates. The younger the age, the faster the pulse. If the rate exceeds the normal range, it is called pulse acceleration. The pulse is the arterial pulsation. With the rhythmic contraction and relaxation of the heart, the arterial wall appears correspondingly dilated and retracted, and the pulsation can be reached on the superficial artery. The pulse is the arterial pulse, and the pulse rate is the pulse rate. Normal people's pulse and heartbeat are consistent. Normal adults are 60 to 100 beats per minute, often 70-80 beats per minute, with an average of about 72 beats per minute. Older people are slower, 55 to 60 beats per minute. The normal pulse rate rule does not cause the pulse interval to vary. The normal person's pulse strength is equal, and there will be no alternating strength or weakness. The frequency of the pulse is affected by age and gender. Infants are 120-140 beats per minute, children are 90-100 beats per minute, and school-age children are 80-90 beats per minute.

Cause

Cause

The cause of pulse acceleration is mostly functional, and can also be seen in organic heart disease and extracardiac factors. Its production is mainly related to sympathetic excitation and decreased vagal tone.

(1) Physiological pulse acceleration: Physiological pulse acceleration is very common. Many factors affect pulse, such as posture change, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, agitation, drinking, smoking, drinking tea. Wait, you can speed up the pulse. In addition, age is also a factor, and children's heart rate tends to be faster.

(2) drug-induced pulse acceleration: such as sympathomimetic drugs such as ephedrine and epinephrine. Parasympathetic blockers such as atropine, caffeine, thyroxine, amphetamine, etc. can cause pulse acceleration.

(3) Pathological pulse acceleration: such as systemic diseases: high fever, anemia, hypoxia, infection, hyperthyroidism, pain, acute rheumatic fever, beriberi and neurosis can cause pulse acceleration.

Pulse pulse wave velocity

The normal pulse rate of the human body is 60-100 beats per minute. When the pulse rate is greater than this range, pulse acceleration can be diagnosed.

During the cardiac cycle, the vessel undergoes periodic expansion and pulsation of the return position due to the alternating ventricular contraction and diastole.

The condition is critical, especially the number and pulse rate of the pulse before dying will change significantly. Pulse changes are also one of the doctors' diagnosis of patients.

Diagnosis

Differential diagnosis

Pulse acceleration symptoms need to be distinguished from the following symptoms.

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 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.

The normal pulse rate of the human body is 60-100 beats per minute. When the pulse rate is greater than this range, pulse acceleration can be diagnosed.
