术后心律失常是先天性心脏病(以下简称先心病)心脏外科术后患病与死亡的主要原因之一[1]。术后心律失常的发生随外科技术的发展及新的外科技术的采用而发生变化。术后早期心律失常常需即刻纠正电解质紊乱及给予药物或非药物干预。术后晚期心律失常与许多危险因素有关,包括手术直接对传导系统的损伤,外科瘢痕造成传导障碍,先前存在的致心律失常病灶以及先心病患者血 Postoperative arrhythmia is one of the main causes of postoperative morbidity and mortality in congenital heart disease (hereinafter referred to as CHD) [1]. Postoperative arrhythmia occurs with the development of surgical techniques and the adoption of new surgical techniques. Early postoperative arrhythmias often require immediate correction of electrolyte disturbances and drug or non-drug intervention. Late postoperative arrhythmias are associated with a number of risk factors, including direct damage to the conduction system during surgery, conductive barriers to surgical scars, preexisting arrhythmogenic lesions, and blood in patients with congenital heart disease
