Hypertension with low heart rate around 55

Hypertension with a heart rate of 55 beats per minute is considered bradycardia. This low heart rate may result from physiological or pathological factors, such as hypothyroidism, myocardial ischemia, or coronary heart disease.

I. Physiological Factors

In terms of physiological causes, bradycardia may occur during sleep or in well-trained athletes due to high vagal tone. In hypertensive patients, a heart rate of 55 beats per minute may simply reflect the normal slowing of the heart during sleep. In such cases, no specific treatment is required, as the heart rate typically returns to normal spontaneously after a short period.

II. Pathological Factors

1. Hypothyroidism

Hypothyroidism refers to decreased thyroid gland function, resulting in reduced production of thyroid hormones and lower circulating hormone levels, which impairs normal bodily functions. Treatment may include levothyroxine tablets or liothyronine sodium tablets.

2. Myocardial Ischemia

Long-standing hypertension can increase cardiac workload, leading to myocardial ischemia and hypoxia, which may impair the function of the sinoatrial node and the cardiac conduction system. Medications such as isosorbide mononitrate tablets or metoprolol tablets may be prescribed for treatment.

3. Coronary Heart Disease

Coronary heart disease is an organic heart condition caused by narrowed blood vessels that impair blood supply to the heart muscle, potentially leading to tissue necrosis. Symptoms can be managed with medications such as atorvastatin calcium tablets or rosuvastatin calcium tablets.

In addition, other pathological causes may include angina pectoris or excessive medication dosage.
