Abstract：Objective To analyze the causes,treatment,and prognosis of acute cardiac tamponade(ACT)and delayed cardiac tamponade(DCT)in patients with arrhythmia treated with radiofrequency Catheter ablation,and provide insights for identifying high-risk patients and preventing complications in the future.Methods A retrospective analysis was conducted on the general clinical data of arrhythmia patients who underwent catheter radiofrequency ablation at the Seventh People's Hospital of Zhengzhou from January 2017 to December 2021.Patients with surgical related pericardial tamponade were grouped according to different types of arrhythmia.The occurrence mechanism,diagnosis and treatment status,and prognosis of pericardial tamponade among different groups of patients were analyzed,and clinical data of ACT and DCT patients during and after surgery were compared and analyzed.Results Among 5 445 patients undergoing catheter radiofrequency ablation,a total of 57 cases(1.05％)experienced pericardial tamponade,including 3 029 cases of atrial arrhythmia,36 cases(1.19％)of surgery related pericardial tamponade,1 446 cases of paroxysmal supraventricular tachycardia,3 cases(0.21％)of surgery related pericardial tamponade,971 cases of ventricular arrhythmia,18 cases(1.85％)of surgery related pericardial tamponade,and a total of 7 cases requiring emergency surgical intervention.The average age of patients with pericardial tamponade was older than that of patients without pericardial tamponade(P＜0.001),radiofrequency ablation for atrial arrhythmia was more prone to pericardial tamponade compared to paroxysmal supraventricular tachycardia(P＜0.05).There was no statistically significant difference in body mass index,intraoperative drainage volume,emergency surgical procedures,ablation success rate,catheterization time,hemostatic drug use,emergency blood transfusion,length of stay in the intensive care unit,and total length of stay among the groups of patients with pericardial tamponade(P＞0.05).A total of 11 patients(0.2％)presented with DCT,with a median onset time of 5 hours postoperatively.The paroxysmal supraventricular tachycardia group was more likely to present with DCT(P＜0.05).Conclusion Despite the incidence of cardiac tamponade during various arrhythmia ablation operation were different,the etiology and prognosis were similar and the total incidence was relative rare.Most of the cases were related to the improper catheter manipulation,which had good prognosis after timely rescue.In addition,more attention should be paid to the DCT after ablation operation as well.
