What is sinus bradycardia and ventricular premature beats?

In general, ventricular premature beats refer to ventricular premature contractions. Sinus bradycardia and ventricular premature contractions may be caused by physiological factors, electrolyte imbalances, hypertension, myocarditis, or coronary atherosclerotic heart disease. It is recommended to seek timely medical attention and receive symptomatic treatment under the guidance of a physician. Specific analyses are as follows:

1. Physiological Factors

If an individual engages in heavy physical labor over a long period, the cardiac load may increase, potentially leading to symptoms such as slowed heartbeat and chest tightness. This is considered a normal physiological phenomenon and typically does not require special treatment. Adequate rest in daily life is usually sufficient.

2. Electrolyte Abnormalities

Electrolytes such as sodium, potassium, calcium, and magnesium play critical roles in maintaining normal cardiac electrical activity. When electrolyte levels are abnormal, they may affect the excitability and conductivity of the heart, leading to sinus bradycardia and ventricular premature contractions. Drinking moderate amounts of light salt water and consuming fresh vegetables and fruits regularly can help alleviate these symptoms.

3. Hypertension

Hypertension, caused by genetic factors or unhealthy lifestyle habits, may increase cardiac workload and trigger compensatory responses in the heart, including sinus bradycardia and ventricular premature contractions. Under medical supervision, medications such as nifedipine tablets, methyldopa tablets, or captopril sustained-release tablets can be used to control blood pressure and relieve symptoms.

4. Myocarditis

When pathogens invade the myocardium and induce inflammation, symptoms such as slowed heartbeat, chest tightness, and dizziness—indicative of sinus bradycardia and ventricular premature contractions—may occur. Treatment may include medications such as amoxicillin capsules, cefixime dispersible tablets, or ribavirin injection, taken as directed by a physician.

5. Coronary Atherosclerotic Heart Disease

Coronary atherosclerotic heart disease, caused by narrowing or blockage of the coronary arteries, may lead to myocardial ischemia, resulting in symptoms such as chest pain and tightness. It may also cause sinus bradycardia and ventricular premature contractions. Under medical guidance, drugs such as simvastatin dispersible tablets, atorvastatin calcium tablets, or isosorbide nitrate tablets may be used to alleviate symptoms.

It is recommended to get adequate rest during periods of stability to help relieve symptoms. Diet should be mild and清淡 (light); avoid spicy and irritating foods such as chili peppers, Sichuan pepper, and garlic, which may worsen symptoms.
