Why does my heart beat fast when I'm waking up from sleep, and what should I do about it?

When waking up from sleep, a rapid heartbeat may be caused by conditions such as cardiac neurosis, anemia, or hypoglycemia. These can be improved through general treatments, medications, and other methods. Specific analyses are as follows:

1. Cardiac Neurosis

Cardiac neurosis is a heart condition caused by dysfunction of the nervous system, which may lead to symptoms such as tachycardia (rapid heart rate) and arrhythmia (irregular heartbeat). During sleep, the balance between the sympathetic and parasympathetic nervous systems may be disrupted, resulting in increased heart rate. It is important to avoid negative emotions such as tension, anxiety, and depression. Symptoms can be relieved through listening to soft music, going on outings, engaging in moderate exercise, or talking with family and friends.

2. Anemia

Anemia refers to a deficiency of sufficient red blood cells or hemoglobin in the body. Due to insufficient oxygen-carrying capacity of the blood, the heart may become overworked, leading to a faster heartbeat. Patients can take medications such as Ejiao Blood-enriching Granules or folic acid tablets under medical supervision to improve symptoms.

3. Hypoglycemia

Hypoglycemia refers to abnormally low blood glucose levels, which may result from excessive insulin secretion or improper diet. Hypoglycemia can cause various discomforts such as dizziness, palpitations, and sweating, all of which may contribute to a rapid heartbeat. Patients should receive treatment under a doctor's guidance, such as intravenous glucose solution or furosemide tablets.

Besides the above causes, a rapid heartbeat upon waking could also be due to hyperthyroidism, coronary atherosclerotic heart disease, or myocardial infarction. Some of these conditions may require surgical intervention. It is advisable to maintain a healthy lifestyle, ensure adequate sleep, and avoid excessive fatigue.
