Disease analysis: There are significant individual differences in resting heart rate of normal adults, with an average of about 75 beats/min (between 60- 100 beats/min). Adult heart rate exceeds 100 beats per minute, which is called tachycardia. There are two kinds of tachycardia: physiological and pathological. Physiological tachycardia is very common, and there are many factors that affect the heart rate, such as body position change, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, excitement, drinking, smoking, drinking tea, etc., which can increase the heart rate. In addition, age is also a factor, and children's heart rate tends to be faster. Pathological tachycardia can be divided into sinus tachycardia and paroxysmal supraventricular tachycardia. Characterized by gradual acceleration and deceleration of the heart rate. Generally, the heart rate will not exceed 140 beats per minute. Most patients have no organic heart disease, patients generally have no obvious discomfort, and sometimes there are symptoms such as palpitation and shortness of breath.
Suggestion: If it is persistent tachycardia, we must find out the cause and treat it as soon as possible.
