A pulse rate (informal term: pulsation) of 90 to 100 beats per minute is generally normal, but if the pulse rate was not so high in the past, but has only recently become elevated, it is also necessary to be vigilant about whether it is caused by disease. Pulse rate influencing factors are generally similar to the heart rate, the normal adult pulse rate in a quiet, awake state of 60 to 100 beats / min, the elderly slower, women a little faster, children faster, healthy people in smoking, tea or coffee, alcohol, physical activity and emotional excitement when the pulse rate can also be higher than the quiet or even more than 100 beats / min. If the heart rate is 90-100 beats/minute when the subject is quiet and awake, and there is no excessive sweating, weight loss, pale conjunctiva, panic and other discomforts, then the pulse rate is generally normal and there is no need to worry too much. If the examinee’s pulse rate is usually not so high, but only recently appeared in the quiet, awake state of 90 ~ 100 beats / min of the pulse rate, we need to be alert to whether there are a variety of causes of fever, or hyperthyroidism, anemia, myocardial ischemia, etc., generally can appear corresponding discomfort, such as excessive sweating, poor mental health, or overeating, weight loss, or conjunctival pallor, fatigue, and there may also be heartburn and other discomforts. If you have abnormal pulse rate, you need to go to the hospital as soon as possible, the doctor according to the specific conditions, to formulate individualized diagnosis and treatment plan, so as not to delay the condition.
