The risk of sudden death will occur when staying up late for a long time, the rhythm of the heart will be disturbed, for example, patients will have frequent premature beats, in addition, patients will have arrhythmias such as paroxysmal supraventricular tachycardia, the above arrhythmias will increase the burden and load on the heart, so it will lead to the possibility of sudden death and other types of situations. For example, the renin-angiotensin-aldosterone system is easily activated, and the patient will have unstable blood pressure, which will also increase the chance of sudden death. In addition, patients who stay up late for a long time will lead to sympathetic overexcitation, so there will be increased cardiac work and insufficient cardiac perfusion, so there is a risk of sudden death from staying up late for a long time.
