What does a female heart rate of around 90 mean

A female resting heart rate of 90 beats per minute is within the upper limit of the normal range and may indicate potential health risks. The main influencing factors include physiological sinus tachycardia, anemia, hyperthyroidism, autonomic nervous system disorders, and early manifestations of cardiovascular disease.

1. Physiological factors:

Daily emotional fluctuations, caffeine intake, or short-term intense exercise can all temporarily increase heart rate. This type of situation usually has no accompanying symptoms, and after removing the trigger, the heart rate can naturally recover to the ideal range of 60-80 beats per minute. Pregnant women who experience an increase in blood volume and a 10-15 beats per minute increase in heart rate compared to pre pregnancy levels are also considered normal physiological phenomena.

2. Anemia effects:

In iron deficiency anemia, the oxygen carrying capacity of hemoglobin decreases, and the heart compensates and accelerates to meet the oxygen supply demand. These patients often have symptoms such as pale complexion and fatigue, and blood routine tests show hemoglobin levels below 110g/L. Supplementing with iron and vitamin C can improve symptoms, but severe anemia requires blood transfusion treatment.

3. Hyperthyroidism may:

Excessive secretion of thyroid hormones can stimulate beta receptors in myocardial cells, leading to persistent tachycardia. The characteristic manifestations include excessive sweating, hand tremors, weight loss, and laboratory tests show elevated FT3 and FT4 levels while TSH levels decrease. Antithyroid drugs such as methimazole can effectively control symptoms, and if necessary, radioactive iodine therapy is needed.

4. Abnormal neural regulation:

Long term anxiety or menopausal autonomic dysfunction can lead to excessive excitation of the sympathetic nervous system. These patients often have symptoms such as insomnia and hot flashes, and heart rate variability testing shows autonomic nervous system imbalance. psychological counseling combined with neuromodulatory drugs such as glutamate can improve symptoms.

5. Cardiovascular warning:

Continuous increase in heart rate may be an early signal of diseases such as hypertension and coronary heart disease. Research shows that individuals with a resting heart rate greater than 84 beats per minute have a 1.34-fold increased risk of cardiovascular events. Suggest improving dynamic electrocardiogram, cardiac ultrasound and other examinations, and using beta blockers to control heart rate if necessary.

It is recommended to monitor the resting heart rate in the morning on a daily basis and maintain 150 minutes of moderate intensity aerobic exercise per week, such as brisk walking, swimming, etc., which can enhance heart function. Pay attention to supplementing foods rich in magnesium, such as nuts and dark green vegetables, and limit caffeine intake. Menopausal women can try stress relieving methods such as yoga and meditation. If their heart rate continues to be above 100 beats per minute or accompanied by symptoms such as chest pain and fainting, they should seek timely medical attention from a cardiologist. Regular physical examinations should include thyroid function, blood routine, and electrocardiogram examinations. It is recommended that individuals over the age of 40 undergo a maximal exercise load test every two years to assess cardiac reserve capacity.
