摘　　要：本例75岁男性患者,在行左心室流出道起源的室性早搏射频导管消融术后出现胸闷、血压降低,且心电图aVR、V_(1)导联ST段抬高,伴多导联ST段压低,冠状动脉造影提示左冠状动脉主干至左前降支夹层,遂于此处置入两枚药物洗脱支架。术后患者生命体征平稳,随访过程中无明显不适。A 75-year old man suffered from chest distress post radiofrequency catheter ablation of premature ventricular contractions originating from the left ventricular outflow tract.Hypotension was diagnosed during physical examination.STsegment elevation in leads aVR and V_(1),and ST-segment depressions in other leads were evidenced in electrocardiogram.Coronary angiography was immediately performed and revealed dissection of the left main coronary artery that extended into the anterior descending artery.Two drug eluting stents were immediately implanted.The vital signs of the patient were stable after stenting,and there was no obvious discomfort during follow-up post discharge.
