目的:探讨急性心肌梗死患者急诊行经皮冠状动脉介入术中再灌注心律失常的特点及防治。方法:回顾性分析82例急性心肌梗死急诊行经皮冠状动脉介入术中发生再灌注心律失常患者的临床资料。结果:<6h开通冠状动脉者再灌注心律失常发生率高于6～12h开通者,明显高于12～24h开通者(P<0.05)。前降支、右冠状动脉梗死再灌注心律失常发生率高,前降支梗死发生快速型心律失常多见,右冠状动脉梗死组发生缓慢型心律失常多见。结论:急性心肌梗死患者急诊行经皮冠状动脉介入术中常发生再灌注心律失常,尤其是心肌梗死发生早期行经皮冠状动脉介入术更易发生。右冠状动脉梗死患者术中缓慢心律失常多见,前降支梗死患者快速心律失常多见。
Objective: To investigate the characteristics and prevention and treatment of reperfusion arrhythmia during emergency percutaneous coronary intervention in patients with acute myocardial infarction. Methods: The clinical data of 82 patients with acute myocardial infarction who underwent percutaneous coronary intervention for reperfusion arrhythmia were retrospectively analyzed. Results: The incidence of reperfusion arrhythmia in patients with coronary artery opening at 6h was significantly higher than that of those with 6-12h opening (P <0.05). The incidence of anterior descending branch and right coronary artery reperfusion arrhythmia is high. Atrial arrhythmia is more common in the anterior descending artery infarction. Slow arrhythmia is more common in the right coronary artery infarction group. Conclusions: Recoronary arrhythmia often occurs in patients undergoing acute percutaneous coronary intervention in acute myocardial infarction. In particular, percutaneous coronary intervention is more likely to occur in early stage of myocardial infarction. Slow right ventricular arrhythmia in patients with right coronary artery occlusion is more common in patients with acute left ventricular arrhythmia.
