Extreme heart rate

Introduction According to statistics, the adult heart rate exceeds 100 beats per minute, which is called heart rate overspeed. Heart rate is divided into two types: physiological and pathological. (1). Physiological heart rate tachycardia Physiological heart rate tachycardia is very common, and many factors affect heart rate, such as body position changes, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, agitation, drinking, smoking, drinking tea, etc., can increase heart rate fast. In addition, age is also a factor in heart rate overspeed, and children's heart rate tends to be faster. (2). Pathological heart rate tachycardia Can be divided into sinus heart rate tachycardia and paroxysmal supraventricular tachycardia: 1. Sinus heart rate tachycardia: It is characterized by rapid heart rate and slowing down. Generally, the heart rate per minute will not exceed 140 times. Most patients have no organic heart disease. Patients with heart rate tachycardia generally have no obvious discomfort, sometimes have palpitation. Shortness of breath and other symptoms. 2. Paroxysmal supraventricular rate: The heart rate can reach 160 to 200 beats per minute, characterized by sudden onset and sudden stop. It can occur in patients with organic lesions in the heart, or in patients without organic heart disease. Suddenly, the patient suddenly felt palpitation and increased heart rate. It lasted for several minutes, hours to days, and suddenly returned to normal heart rate. At the time of the attack, the patient felt palpitations, chest tightness, discomfort in the anterior region and swelling of the head and neck, and a sense of jumping. People without heart disease generally have no major impact, but the attack time is long. When the heart rate is more than 200 beats per minute, the patient has black eyes, dizziness, fatigue, nausea and vomiting, and even sudden syncope and shock due to blood pressure drop. Heart rate tachycardia in patients with coronary heart disease can induce angina pectoris. If you have sustained heart rate tachycardia, you must identify the cause and target the disease early.

Cause

1, hyperthyroidism: may have heart rate, palpitations, sweating, insomnia, increased appetite, weight loss, etc.;

2, fever, anemia;

3, cardiovascular disease: pay special attention to myocarditis;

4, autonomic dysfunction: such as -receptor hypersensitivity, menopausal syndrome, etc. can also occur sinus heart rate tachycardia.

Electrocardiogram

Adult sinus node impulse formation rate exceeds 100 beats per minute, called heart rate, and the rate is often between 101-160 beats per minute. When the heart rate starts and ends quickly, its heart rate gradually increases and slows down. The electrocardiogram shows sinus P waves, the P wave rate exceeds 100 beats per minute, and the PR interval is greater than 0.12 seconds.

Differential diagnosis

The diagnosis should be differentiated from the following symptoms:

1. Heart rate increases People of different ages have different heart rates. The younger the age, the faster the heart rate. If the heart rate exceeds the normal range, it is called heart rate too fast. Parents generally know that normal people will have a faster heart rate after exercise or physical labor. This is also true of children, especially when they are scared or crying.

2. Heart rate is too slow Normal people's heart rate is 60 ~ 100 beats / min, less than 60 is called bradycardia. There are several types of bradycardia, the most common being sinus bradycardia. Sinus bradycardia can be divided into pathological and physiological. Physiological sinus bradycardia is a normal phenomenon. The general heart rate and pulse rate are 50-60 beats/min. The athlete may have 40 heart rate. Without treatment, it is common in normal people who sleep and have more physical activity. Heart rate or pulse is less than 50 times. Most of them are pathological and require treatment. In severe cases, a pacemaker should be installed to speed up the heart rate.

3. Heart rate irregularity Arrhythmia is a pathological phenomenon in which heart pulsation is abnormal due to heart disease.
