Generally speaking, fast heartbeat during sleep may be caused by physiological factors such as being frightened or over-excited before going to bed, or pathological factors such as hyperthyroidism and hypoglycemia, etc. It can be treated by general therapy and medication.
1. Physiological factors: If the patient is frightened or over-excited before going to bed, drinking coffee, strong tea, etc., it may lead to rapid heartbeat during sleep. Generally, there is no need to worry too much, usually pay attention to rest, you can drink a glass of warm milk before going to bed to relieve.
2. Pathological factors
(1) Hyperthyroidism: The thyroid gland synthesizes and releases too much thyroid hormone during sleep, which results in an exuberant metabolism and leads to symptoms such as dreaminess and rapid heartbeat. Generally, it can be treated with medicines such as propylthiouracil tablets and methimazole tablets under doctor’s guidance.
(2) Hypoglycemia: Low glucose content in blood plasma increases blood pressure at night during sleep, and the sympathetic nerves are abnormally excited, resulting in hypoxia of brain cells, which in turn causes rapid heartbeat. Generally, it can be treated with drugs such as phenytoin sodium tablets and glucose injection under doctor’s guidance.
In addition, insomnia, heart failure, etc. may also cause rapid heartbeat during sleep, and the patient should go to the hospital in time for consultation and treatment.
