The most common cause of electrical storms is acute myocardial ischemia resulting in electrophysiological abnormalities in cardiomyocytes. sympathetic hyperexcitability and beta receptor hyperresponsiveness are the pathogenesis of electrical storms. electrical storms in ACS occur mostly in patients with acute myocardial infarction (AMI), with occlusion of the anterior descending branch or proximal right coronary artery, especially in early ST-segment elevation myocardial infarction (STEMI), with a high incidence of ventricular fibrillation and a high rate of sudden death . Some data show that the incidence of ventricular fibrillation in STEMI patients is 4%-8%, of which 60% occurs within 4 hours of onset and about 80% occurs within 12 hours of onset. For some patients with cardiac insufficiency or reduced left ventricular heart function (LVEF), it can also occur after hemodynamic reconstruction, which is the case in this patient.
