摘要 【目的】探讨心电图QT间期与变异型心绞痛患者室性心律失常的相关性。【方法】回顾性分析本院收治的74例变异型心绞痛患者临床资料,根据发作时与不发作时的校正QT间期,将患者分为观察组(QT间期缩短,n=34)和对照组(QT间期正常,n=40)。比较两组室性期前收缩负荷、发生室速比例、QT值及治疗疗效。【结果】观察组室性期前收缩负荷、室速比例高于对照组,QT值、LVEF均低于对照组,差异有统计学意义(P<0.05)。观察组治疗有效率为52.94%(18/34)明显低于对照组的80.00%(32/40),差异有统计学意义(χ2=6.141,P=0.013<0.05)。采用Pearson线性相关分析显示,QT间期缩短与变异型心绞痛患者室性心律失常的发生有显著相关性(r=0.46,P=0.035<0.05)。【结论】变异型心绞痛发生QT间期缩短的患者,其发生室性期前收缩负荷和室速比例明显上升,同时其抗心律失常治疗的效果较差,临床工作者应根据相关心电图检查结果尽早给予及时有效的治疗。

Abstract【Objective】To explore the correlation between electrocardiogram QT interval and ventricular arrhythmia in patients with variant angina pectoris. 【Methods】The clinical data of 74 patients with variant angina pectoris in our hospital were retrospectively analyzed. According to the corrected QT interval between attack and non-attack, the patients were divided into observation group (shortened QT interval, n=34) and control group (normal QT interval, n=40). The ventricular premature systolic load, the proportion of ventricular tachycardia, the value of QT and the therapeutic effect were compared between the two groups.【Results】The proportion of premature ventricular systolic load and ventricular tachycardia in the observation group was higher than that in the control group, while the value of QT and LVEF were lower than those in the control group (P<0.05). The effective rate of the observation group was 52.94% (18/34), which was significantly lower than that of the control group 80.00% (32/40). There was a significant difference between the two groups (χ2=6.141,P=0.013<0.05). Pearson linear correlation analysis showed that shortened QT interval was significantly correlated with ventricular arrhythmia in patients with variant angina pectoris (r=0.46,P=0.035<0.05). 【Conclusion】The proportion of premature ventricular systolic load and ventricular tachycardia increase significantly in patients with variant angina with shortened QT interval, and the effect of antiarrhythmic therapy is poor. Clinicians should give timely and effective treatment as soon as possible according to the results of relevant electrocardiogram examination.
