摘 要 1例77岁男性陈旧性下壁心肌梗死患者入院行经皮冠状动脉介入(PCI)治疗,术后第2天突发胸闷,心电图示频发室性早搏,给予改善心肌血供、维持电解质平衡及抗心律失常治疗后病情逐渐稳定。考虑频发室性早搏与PCI术、血钾偏低、不规范使用胺碘酮及患者睡眠差、情绪紧张相关。

ABSTRACT A 77-year-old man with old inferior wall myocardial infarction was hospitalized for percutaneous coronary intervention. On the second day after surgery, the patient suddenly felt dyspnea. The electrocardiogram showed frequent ventricular premature contractions. The patients condition was gradually stabilized after improving blood supply, maintaining electrolyte balance and using antiarrhythmic agents. Frequent ventricular premature contractions might be associated with percutaneous coronary intervention, potassium depletion, irregular use of amiodarone, poor sleep and emotional stress.
KEY WORDS old myocardial infarction; frequent ventricular premature contractions; amiodarone
室性早搏是一种最常见的心律失常,正常人或各种心脏病患者均可发生。缺血、缺氧、麻醉、手术、药物、电解质紊乱、不良的情绪和生活方式是常见诱发因素。无器质性心脏病者发生室性早搏不会增加心脏性死亡的危险性,但对于有器质性心脏病患者尤其是急性心肌缺血者发生室性早搏可能是致命性室性心律失常的先兆。现报告一例陈旧性心梗经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后出现频发室性早搏的治疗过程并分析发生室性早搏的原因,以期引起临床的重视,减少此类心律失常的发生。
1 病史摘要
患者,男性,77岁,因“反复胸闷、气促13年余,加重半年余” 入院。
患者自诉于1998年无明显诱因出现持续性胸痛,当地医院根据心电图和心肌酶动态变化诊断“急性心肌梗死”,经治疗后病情好转(具体不详)。近10年来胸闷、气促反复出现,近半年较前加重,每次发作持续半小时至数小时不等,胸闷严重时伴有出汗,无明显胸痛,无夜间阵发性呼吸困难及双下肢浮肿。1月前在外院就诊,胸片示:两肺纹理增多;……
