Is it normal for a heart rate of over 90 in a static state

A heart rate of over 90 beats per minute in a static state is within the upper limit of the normal range, but it needs to be evaluated based on individual differences. Heart rate is influenced by factors such as age, physical fitness level, emotional state, underlying diseases, and medication.

1. Age factor:

Adolescents generally have a faster resting heart rate, with 60-100 beats per minute being normal; Middle aged and elderly people with heart rates exceeding 90 beats per minute should pay attention to cardiovascular risks. Menopausal women may experience sinus tachycardia due to hormonal changes, but it is usually accompanied by symptoms such as hot flashes.

2. Physical fitness level:

Long term exercise individuals can have a resting heart rate as low as 50-60 beats per minute, while sedentary individuals tend to have a faster heart rate. Continuous aerobic exercise for three months can reduce heart rate by 5-10 times, and endurance training such as swimming and jogging has significant effects.

3. Emotional impact:

Anxiety, tension, and other emotions can increase heart rate through sympathetic nervous system excitation. Before measurement, it is necessary to sit quietly for 15 minutes. Persistent stress state may lead to cardiac neurosis, manifested as palpitations accompanied by insomnia.

4. Pathological factors:

Metabolic diseases such as hyperthyroidism and anemia are often accompanied by increased heart rate, usually exceeding 100 beats per minute. Mild myocarditis and early heart failure may result in a resting heart rate of 90-100 beats per minute, which should be judged in conjunction with symptoms of chest tightness and shortness of breath.

5. Drug effects:

Asthma patients taking salbutamol, hyperthyroidism patients taking medication such as levothyroxine can accelerate heart rate. A daily intake of over 400 milligrams of caffeine, about 4 cups of coffee, can increase heart rate 5-15 times.

It is recommended to measure resting heart rate every morning and record the trend of changes, avoiding consuming stimulating drinks 30 minutes before the measurement. Regular soothing exercises such as Tai Chi and yoga can improve autonomic nervous system regulation. Pay attention to supplementing magnesium rich foods such as pumpkin seeds and dark chocolate in your diet, which can help stabilize your heart rhythm. If the heart rate continues to exceed 100 beats per minute or accompanied by dizziness and chest pain, 24-hour dynamic electrocardiogram monitoring is required.
