Sleeping easily woke up panic may be physiological factors, such as mood swings, etc., may also be the symptoms of certain diseases, such as arrhythmia, coronary heart disease, cardiogenic asthma. 1. Physiological factors: when the daily life of excessive stress, mood swings, etc., sleep shallow and easy to dream, which leads to sympathetic nerve excitation, resulting in a faster heart rate, increased blood pressure, which is easy to sleep suddenly woke up the phenomenon of panic. Sleep quality should be improved by maintaining a good mood and avoiding overwork. 2. Arrhythmia: patients with arrhythmia may have tachyarrhythmia during sleep due to the increased excitability of the heart muscle, resulting in tachyarrhythmia, which is prone to the phenomenon of sudden awakening and panic attacks during sleep. 3. coronary heart disease: coronary heart disease patients in the process of sleeping may appear coronary artery spasm, insufficient blood supply and other conditions, resulting in the heart rate of compensatory acceleration, thus appearing in the sleep suddenly woke up the phenomenon of panic. 4. Cardiogenic asthma: that is, when the left heart failure, due to the left heart insufficiency leads to pulmonary stasis, and in the sleep of the vagus nerve excitability, while lying posture will aggravate the pulmonary stasis, resulting in hypoxia dyspnea, accelerated heart rate, thus easy to cause the symptoms of waking up panicky in bed. If after excluding the physiological factors, the patient still recurs to sleep easily waking up panic symptoms, should go to the hospital in time for examination, to identify the cause of the disease, under the guidance of a professional doctor for standardized treatment, so as to avoid delays in the condition, resulting in adverse consequences.
