摘　　要：目的：探讨室性心律失常的发生与陈旧性心肌梗死 fQRS 波的相关性。方法选取2012年1月至2014年12月收治的70例陈旧性心肌梗死患者为本研究对象，于入院72 h 内依据心电图 fQRS 观察结果，将其分为A 组[伴有 fQRS，其中 A1组（2个导联）、A2组（﹥2个导联）]、B 组（未出现 fQRS），观察各组住院期间室性心律失常发生情况，探讨室性心律失常的发生与陈旧性心肌梗死 fQRS 波之间的相关性。结果 A 组室扑/室颤（13.63％vs 0）、单形/多形室速（20.45％ vs 3.84％）、多形/多源室早（22.72％ vs 3.84％）、单源室早（47.72％ vs 30.76％）、成对室早（25.00％ vs 7.69％）、频发室早（27.27％ vs 15.38％）、偶发室早发生率（34.09％ vs 23.07％）均较 B 组高，A1组室扑/室颤（0 vs 20.00％）、单形/多形室速（5.26％ vs 28.00％）、多形/多源室早（10.52％ vs 36.00％）、单源室早（26.31％ vs 56.00％）、成对室早（0 vs 20.00％）、频发室早（5.26％ vs 32.00％）、偶发室早发生率（10.52％ vs 40.00％）均较 A2组低，差异有统计学意义（ P ﹤0.05）。结论室性心律失常的发生与陈旧性心肌梗死 fQRS 波之间具有密切相关性，伴有 fQRS 波的陈旧性心肌梗死者具有较高的室性心律失常发生率，临床上应引起足够重视。Objective To investigate the relationship between the fQRS wave of myocardial infarction and the hap-pening of ventricular arrhythmia. Methods Seventy patients with old myocardial infarction in the hospital from January to December 2014 were taken as the objects of this research. On the basis of fQRS on electrocardiogram,the results were ob-served within 72 h after patients’admission. Then they were divided into the group A with fQRS,in which there were 2 leads in group A1 and 2 leads in group A2 with no fQRS in group B. The occurrence of ventricular arrhythmias of each group was observed during the hospitalization. The correlation between the occurrence of ventricular arrhythmia and fQRS wave of old myocardial infarction. Results Ventricular fibrillation of group A（13. 63% vs 0）,single shape/ polymorphic ventricular tachycardia（20. 45% vs 3. 84% ）,pleomorphic/ polymorphic ventricular premature（22. 72% vs 3. 84% ）, single source of ventricular premature（47. 72% vs 30. 76% ）,pair ventricular premature（25% vs 7. 69% ）,frequent premature ventricular contraction（27. 27% vs 15. 38% ）and incidental chamber（34. 09% vs 23. 07% ）were all higher than those in the group B. For group A1,ventricular fibrillation was（0 vs 20% ）,single shape/ polymorphic ventricular tachycardia（5. 26% vs 28% ）,pleomorphic/ polymorphic ventricular premature（10. 52% vs 36% ）,single source of ven-tricular premature（26. 31% vs 56% ）,pair ventricular early（0 vs 20% ）,frequent premature ventricular contraction （5. 26% vs 32% ）and the incidence of early sporadic chamber（10. 52% vs 40% ）were all lower than that of group A2. The differences were significant（P ﹤ 0. 05）. Conclusions There’s close correlation between the ventricular arrhythmia and fQRS wave of myocardial infarction. Patients who have myocardial infarction with fQRS wave own higher occurrence rate of ventricular arrhythmia,so enough clinical attention should be paid.
