Extreme heart rate

According to statistics, an adult heart rate of more than 100 times per minute is called heart rate tachycardia. Heart rate tachycardia is divided into two types: physiological and pathological. (1) Physiological tachycardia Physiological tachycardia is very common, many factors affect the heart rate, such as body position changes, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, agitation, drinking, smoking, drinking Tea, etc., can make your heart rate faster. In addition, age is also a factor in tachycardia, which is often faster in children. (2). Pathological tachycardia can be divided into two types: sinus tachycardia and paroxysmal supraventricular tachycardia: 1. sinus tachycardia: characterized by the gradual increase and decrease of heart rate Generally, the heart rate does not exceed 140 beats per minute, and most of them have no organic heart disease. Patients with tachycardia generally have no obvious discomfort, and sometimes have symptoms such as palpitation and shortness of breath. 2. Paroxysmal supraventricular tachycardia: The heart rate can reach 160 to 200 times per minute, which is characterized by sudden onset and sudden stop. Can occur in patients with organic heart disease, but also in patients without organic disease. The patient suddenly felt panic and increased heart rate during the attack, which lasted for several minutes, hours to days, and suddenly returned to normal heart rate. At the time of the attack, the patient was conscious of palpitations, chest tightness, discomfort in the anterior heart area, and swelling and beating of the head and neck. Those without heart disease generally have no major impact, but have a long attack time. When the heart rate is more than 200 beats per minute, due to blood pressure drop, patients with dark eyes, dizziness, fatigue, nausea and vomiting, and even sudden syncope and shock. Heart rate tachycardia in patients with coronary heart disease can induce angina. If you have persistent tachycardia, be sure to identify the cause and treat the cause early.
