The electrocardiogram in As syndrome is characterized by significant arrhythmias, often severe bradycardia or ventricular tachycardia or ventricular fibrillation, which can be life-threatening depending on the specific manifestations, including slow and fast arrhythmias. Depending on the severity of the condition, the electrocardiogram may vary, making it a more serious arrhythmia. The situation is more urgent and can manifest as ventricular fibrillation, which requires prompt cardiopulmonary resuscitation to improve the functional status of the heart and restore the normal pumping state of the heart. In case of As syndrome, there will be clinical manifestations such as unconsciousness and twitching of limbs. The patient’s blood circulation should be restored in time to ensure cardiopulmonary, renal and cerebral functions, and symptomatic support treatment should be sought in time for recurrent patients.
