Is it normal for a heartbeat to remain between 80-90 for a long time

Maintaining a heartbeat of 80-90 beats per minute for a long time is considered normal and may be associated with physiological factors or potential health problems. The main influencing factors include daily activity level, emotional state, underlying diseases, drug effects, and metabolic abnormalities.

1. Physiological factors:

Long term lack of exercise, anxiety and tension, or excessive intake of caffeine may all lead to a high resting heart rate. The sedentary population in the office often experiences compensatory enhancement of cardiovascular and pulmonary function, resulting in heart rate being at the upper limit of the normal range; Excitement of the sympathetic nervous system during emotional fluctuations can also cause a brief increase in heart rate, and if it persists for a long time, it may lead to habitual acceleration.

2. Cardiovascular risk:

Early hypertensive patients often experience an increase in resting heart rate, which may be related to increased vascular resistance. When hyperthyroidism occurs, the basal metabolic rate increases and the heart rate often remains above 90 beats per minute, accompanied by symptoms such as fear of heat and hand tremors. This type of situation needs to be diagnosed through dynamic electrocardiogram and thyroid function examination.

3. Drug effects:

Long term use of β 2 receptor agonists, serotonin reuptake inhibitors in antidepressants, and thyroid hormone replacement therapy drugs in some asthma patients may cause an increase in heart rate. Suggest recording medication history and communicating with the attending physician to adjust the plan.

4. Abnormal metabolism:

Autonomic neuropathy in diabetes patients can lead to abnormal heart rate regulation, and anemia patients will have sustained tachycardia due to compensatory mechanism. This type of situation needs to be comprehensively judged by combining blood glucose monitoring, blood routine examination, and other tests.

5. Physical differences:

Some healthy individuals may have naturally high or low baseline heart rates due to genetic factors or long-term endurance training. Due to the increase in stroke output, athletes' resting heart rate is often below 60 beats per beat, while those with slim body types have relatively faster heart rates.

It is recommended to monitor the resting heart rate in the morning on a daily basis, and measuring it continuously for one week can more accurately reflect the baseline state. You can try aerobic exercise such as brisk walking, swimming, etc. to enhance cardiovascular function, ensure 7 hours of sleep per day, and limit caffeine intake. If accompanied by symptoms of chest tightness, dizziness, or a family history of premature heart disease, a 24-hour dynamic electrocardiogram examination is required. Controlling weight between BMI 18.5-24 and maintaining blood pressure below 120/80mmHg can help the heart rate naturally fall back to the ideal range.
