What should I do if my heart rate keeps above 100

Sinus tachycardia with a heart rate exceeding 100 beats per minute can be improved through lifestyle adjustments, medication control, and etiological treatment. Common causes include physiological stress, anemia, hyperthyroidism, etc.

1. Physiological factors:

Intense exercise, emotional tension, or consumption of caffeinated beverages may cause a temporary increase in heart rate. It is recommended to relax the parasympathetic nervous system through deep breathing exercises, soaking feet in warm water, and avoiding the intake of irritating substances such as strong tea and alcohol in daily life. continuously monitor resting heart rate. If it does not return within 48 hours, seek medical attention for investigation.

2. Anemia correction: When hemoglobin is below 110g/L, compensatory acceleration of cardiac pumping may cause tachycardia. Complete blood routine and iron metabolism tests are needed. Mild anemia can be improved by increasing iron rich foods such as red meat and animal liver. For moderate to severe anemia, iron supplements or vitamin B12 should be supplemented under the guidance of a doctor.

3. Hyperthyroidism management:

Excessive secretion of thyroid hormones can accelerate myocardial contraction, accompanied by symptoms such as hand tremors and weight loss. Diagnosis requires examination of FT3, FT4, and TSH indicators. Treatment includes antithyroid drugs such as methimazole and radioactive iodine therapy, while limiting the intake of high iodine foods such as seaweed.

4. Electrolyte imbalance:

Hypokalemia or hypomagnesemia can induce arrhythmia, commonly seen after diarrhea and diuretic use. When the electrocardiogram shows a low T wave or an increased U wave, it is necessary to correct it through oral potassium supplements or intravenous fluids. Daily consumption of potassium rich foods such as bananas and spinach should be increased.

5. Heart disease: Organic diseases such as myocarditis and heart failure may lead to persistent tachycardia, accompanied by chest tightness and paroxysmal nocturnal dyspnea. Cardiac ultrasound and dynamic electrocardiogram examination are required, and beta blocker metoprolol or calcium channel blocker diltiazem can be used as basic medication.

It is recommended to measure resting heart rate every morning and record the trend of changes, maintain 150 minutes of moderate intensity aerobic exercise such as brisk walking and swimming per week, and avoid sudden intense exercise. Lack of sleep can increase the burden on the heart, ensuring 7-8 hours of high-quality sleep. Sudden palpitations accompanied by chest pain, blurred vision, and other symptoms require immediate emergency treatment. Long term unrelieved tachycardia may increase myocardial oxygen consumption. It is recommended to review electrocardiogram and echocardiography every 3-6 months to evaluate cardiac function.
