Atrial fibrillation does not heal on its own. The heart rate can reach more than 300 beats per minute during atrial fibrillation episodes, and the condition can worsen with age. Atrial fibrillation is a common arrhythmia with irregular and fast heartbeat, accompanied by panic, shortness of breath and dizziness. It is usually caused by cardiovascular diseases such as hypertension, coronary heart disease, endocrine diseases such as hyperthyroidism, and may also be related to long-term heavy alcohol consumption and sleep deprivation, and may return to normal sinus rhythm with timely medication, but is prone to recurrence. If treatment is delayed and delayed for a long time, thrombus may form in the atria. Once thrombus is formed, atrial fibrillation is almost impossible to recover and can lead to complications such as cerebral artery embolism and coronary artery embolism. The phenomenon of atrial fibrillation should be reviewed regularly by cardiovascular medicine. Exercise reasonably, eat a balanced diet, avoid smoking, drinking alcohol, staying up late for a long time, overworking, and drinking less strong tea and coffee.
