My heart rate has been around 120 for a while. Is this normal?

Whether the human heart rate is normal or not is a criterion for judging whether a person's physical condition is normal. When the heart rate is fast, it is very easy to have heart disease, and a relatively low heart rate means that the person is healthy. Some people have a heart rate of around 120, and they don't know whether this situation is normal. So, is it normal for the heart rate to be around 120 for a while?

First, is it normal that the heart rate has been around 120 for a while? Heart rate (hr) refers to the number of heart beats per unit time. Regular aerobic exercise can make the total heart volume index significantly greater than that of those who do not exercise. The heart tends to grow larger, not only increasing the heart capacity and ventricular wall thickness, but also significantly expanding the ventricular cavity. Ventricular enlargement helps increase ventricular filling volume, improves the heart's functional reserve, and reduces the trainee's heart rate. During long-term regular exercise, the body will produce a series of adaptive changes. The adaptability of heart rate changes shows that the resting heart rate gradually decreases with the improvement of exercise level, the heart rate level decreases when completing the same load, and the maximum heart rate slows down with age; in human aerobic exercise training, some researchers have used 60%-70% of their maximum heart rate (heart rate during exercise = 180) for middle-aged women to perform aerobics or yangko dance exercises. The experimental results show that the aortic valve activity and performance of the exercise group are better than those of the control group, the heart contractile function is greatly improved, and the stenosis or abnormality caused by senile lesions, calcification and adhesion of the aortic valve is delayed. This shows that aerobic exercise can help enhance the heart function of middle-aged and elderly women and regulate their heart rate.

Second, a person's resting heart rate is 60-100 beats/minute, with an average of about 75 beats/minute. The exercise heart rate varies according to the intensity of the exercise. The heart rate of low- to medium-intensity exercise is between 110 and 140 beats per minute. The heart rate of more intense exercise such as weight loss is between 160 and 180 beats per minute. The maximum does not exceed 210 beats per minute. This situation is already considered tachycardia. If it is caused by drinking, it may get better after a period of time. However, drinking generally does not cause heart disease. Your situation may be that you already have heart disease and drinking has become a "trigger". Take a rest for a while and consult some available drugs.

Is it normal for the heart rate to be around 120 for a while? It may be caused by hyperthyroidism, anemia or heart disease. You can take metoprolol or propranolol to temporarily control your heart rate. The standard should be 75 beats per minute. The normal range is: 60-100 beats per minute. The human heart is a hollow muscular organ, slightly conical, located in the mediastinum, between the chest cavity and the two lungs. The heart is tilted to the left, with the base on top and the apex facing down. It is about 10 cm long and weighs about 300 grams, which is about the same size as your fist. The heart is a pump that beats continuously before and after birth until death, continuously supplying blood to the human body. Over a period of 70 years, each ventricle can output 200 million liters of blood. A normal person's heart beats 70 times per minute, and each heart cycle is about 0.8 seconds, of which 0.3 seconds is used for myocardial contraction and 0.5 seconds is used for myocardial relaxation. The heart is divided into the right heart and the left heart. Every time the myocardium contracts, about 70 to 80 ml of blood enters the pulmonary circulation from the right heart; the same amount of blood enters the systemic circulation from the left heart. Therefore, in a calm state, about 5 liters of blood are discharged from the ventricles per minute, but during strenuous exercise, this can increase to more than 25 liters. So it's not normal.
