If the heart beats vigorously during sleep, the patient should measure the pulse himself. If the pulse is below 120 beats/min, the patient can take deep breaths appropriately and calm down at the same time to relieve the emotion, and do not pay too much attention to the heartbeat. If the heartbeat is particularly fast, perhaps above 120 beats/min, the patient should have an electrocardiogram promptly. Younger patients may have arrhythmias such as paroxysmal supraventricular tachycardia, and the patient can alleviate the rapid heartbeat by deep breathing, breath-holding, cold water on the face, and massaging the carotid sinus after a clear diagnosis. However, some patients may only feel that their heartbeat is too fast and their heart rate is within the normal range, which may be caused by their own abnormal sensation. Many thin patients will have a more intense heartbeat after lying down, with the large blood vessels in the heart and abdomen closer to the chest wall and abdominal wall, and the patient mainly needs to divert their attention.
