Premature beats after waking up from a nap are usually caused by autonomic dysfunction and heart disease.
1. Autonomic dysfunction: Autonomic dysfunction sometimes occurs after a nap, which is usually caused by excessive mental tension and stress. When autonomic dysfunction occurs, the balance between sympathetic and parasympathetic nerves is disrupted, and the physiological activities under their control are also disrupted, which may result in premature beats.
2. Heart disease: heart disease such as coronary heart disease, hypertensive heart disease, waking up after a nap is very easy to premature beats. When waking up too quickly after a nap, premature beats may also occur due to an imbalance in autonomic nervous system regulation.
Patients are advised to go to the hospital for an ECG or 24-hour ambulatory ECG, which can initially rule out heart disease.
