The common reasons for waking up with a fast heartbeat are physiological factors such as lack of sleep, as well as hyperthyroidism, coronary heart disease and heart failure.
1. Lack of sleep: If you don’t get enough sleep and are suddenly woken up by the alarm clock, the cerebral cortex will be stimulated, triggering vegetative nervous system dysfunction, and the phenomenon of waking up with a fast heartbeat will occur.
2. Hyperthyroidism: after waking up from sleep, because of hyperthyroidism, the body secretes too much thyroid hormone, which can lead to elevated sympathetic excitability, which can result in increased contractility of the heart muscle, the heart will beat especially fast.
3. Coronary heart disease: If because of cholesterol or other deposits composed of plaque accumulation in the inner wall of the coronary arteries, resulting in coronary artery stenosis or occlusion and cause coronary heart disease. After waking up from sleep the body’s various functions begin to recover, the amount of oxygen needed to increase, and the heart can not get enough oxygenated blood, so there will be a particularly fast heartbeat.
4. Heart failure: heart failure is often caused by myocardial infarction, myocarditis, coronary heart disease and other diseases, because the ventricular contraction function and the heart pumping function is impaired, so sleep after waking up the cardiac load increases, it will happen to heartbeat especially fast.
If you sleep and wake up heart beat particularly fast, to go to the regular hospital to identify the cause of the disease in a timely manner, and under the guidance of a professional doctor to choose the appropriate method for their treatment.
