This case report describes the successful management of a 45-year-old female patient with incessant premature atrial complexes (PACs) leading to left ventricular dysfunction. Despite initial treatment with beta-blockers, the patient's PACs persisted, prompting catheter ablation. Mapping in the left atrium identified the site of earliest atrial activation near the right superior pulmonary vein, and radiofrequency energy successfully terminated the PACs. Follow-up assessments showed the patient remained asymptomatic, with normalized left ventricular function. This case highlights the efficacy of catheter ablation in resolving PAC-induced cardiomyopathy and emphasizes the need for further research in this area.
本病例报告描述了一名45岁患有持续性房性早搏（PACs）并导致左心室功能障碍的女性患者的成功治疗。尽管最初使用β受体阻滞剂进行治疗，但患者的房性早搏仍持续存在，促使进行导管消融。左心房标测确定了右上肺静脉附近最早心房激动的部位，射频能量成功终止了房性早搏。随访评估显示患者仍无症状，左心室功能恢复正常。本病例突出了导管消融在解决PAC诱发的心肌病方面的疗效，并强调了该领域进一步研究的必要性。
