Sleep rolling over with fast heartbeat, the possible causes are vegetative nerve function disorder, cardiac arrhythmia, myocardial ischemia, elevated blood pressure, hypoglycemia and other conditions, frequent episodes, you need to formalize to the hospital, check and clarify the cause, and give treatment. Rapid heartbeat during sleep turning over may be phytoneurologic dysfunction. Generally, the heart rate is slow during sleep, but when you wake up and roll over, the sympathetic nerves are abnormally excited, and the heart rate may increase. Rest and observation is recommended. Possible causes are also arrhythmia, if the turn over occurs sinus tachycardia, paroxysmal atrial fibrillation, supraventricular tachycardia and other cardiac arrhythmias, may occur rapid heartbeat, need to check the electrocardiogram or 24-hour dynamic electrocardiogram, clear arrhythmia type, give propafenone, amiodarone, metoprolol and other drugs, if necessary, the feasibility of radiofrequency ablation treatment. If the blood pressure fluctuation occurs when sleeping and turning over, the blood pressure is elevated, it will reflexively accelerate the heart rate, monitoring blood pressure can be clarified, if the blood pressure is elevated, it is necessary to take oral amlodipine and other antihypertensive drugs to stabilize the blood pressure. If it is a nocturnal attack, there is also the possibility of hypoglycemia, if the heart rate is fast, accompanied by sweating and hunger, it is recommended to monitor the peripheral blood glucose, and if hypoglycemia, pay attention to timely food.
