Why can I always hear my heartbeat when lying flat to sleep, and what should I do about it?

When lying flat during sleep, frequently hearing one's heartbeat may be caused by factors such as neural reflexes, hypertension, or myocarditis. This can be improved through psychological adjustment, medication, and other approaches. Specific analyses are as follows:

1. Neural Reflex

During sleep, the environment is quiet and the body gradually relaxes, making hearing more sensitive and allowing the heartbeat to be clearly perceived. This is a normal physiological phenomenon that does not require special treatment. It is important to maintain a healthy mental state and avoid excessive stress.

2. Hypertension

The exact cause of hypertension is not fully understood but may be related to unhealthy lifestyle habits, genetic factors, and others. After onset, increased blood flow velocity leads to enhanced cardiac contractility, resulting in symptoms such as rapid heartbeat and noticeable heart sounds. Antihypertensive medications such as nifedipine sustained-release tablets or levamlodipine besylate tablets may be taken orally under medical guidance, effectively lowering blood pressure and relieving symptoms.

3. Myocarditis

Viral infections can damage the myocardium, leading to inflammatory changes. Repeated stimulation by inflammatory factors alters cardiac rhythm, causing symptoms such as accelerated and pronounced heartbeat. Treatment may include oral administration of medications such as oseltamivir phosphate capsules or coenzyme Q10 tablets, under medical supervision.

In addition to the above relatively common causes, this symptom may also result from conditions such as cardiomyopathy, hyperthyroidism, or coronary atherosclerotic heart disease. Patients should visit a hospital for comprehensive examinations and follow appropriate treatments as advised by physicians.
