. Takotsubo cardiomyopathy is associated with increased risk of ventricular arrhythmias, atrial fibrillation, and bradyarrhythmias. However, sinus node dysfunction is relatively infrequent in the setting of takotsubo cardiomyopathy. . We are reporting a case of a 73-year-old woman with a history of asymptomatic sinus bradycardia who developed sick sinus syndrome complicated by takotsubo cardiomyopathy. . Acute symptomatic sick sinus syndrome in patients with preexisting silent sinus node dysfunction can trigger takotsubo cardiomyopathy. Understanding precipitating factors of takotsubo cardiomyopathy and identifying the patients at risk of life-threatening arrhythmia can help in refining risk stratification and therapy planning. Patients with sick sinus syndrome complicated by takotsubo cardiomyopathy may benefit from pacemaker implantation. However, evaluation on a case-by-case basis is mandatory.
应激性心肌病与室性心律失常、心房颤动及缓慢性心律失常风险增加相关。然而，在应激性心肌病背景下，窦房结功能障碍相对少见。我们报告一例73岁女性患者，有无症状性窦性心动过缓病史，发生了病态窦房结综合征并伴有应激性心肌病。既往存在隐匿性窦房结功能障碍的患者出现急性症状性病态窦房结综合征可引发应激性心肌病。了解应激性心肌病的诱发因素并识别有危及生命心律失常风险的患者有助于完善风险分层及治疗规划。合并应激性心肌病的病态窦房结综合征患者可能受益于起搏器植入。然而，必须逐例进行评估。
