目的对宽QRS波群心动过速的临床诊断和特征进行系统分析。方法回顾分析我院诊治的85例室上性宽QRS心动过速患者的临床资料,均进行12导联体表心电图检查,同时应用Brugada四步诊断法和室速诊断,分析和总结临床特征、血流动力学及心电图等情况。结果本组85例患者中,78例诊断为室上速伴束支阻滞或者心室内差异性传导,特异性91.8%,敏感性100%;根据心室率分析,<180bpm患者和>180bpm患者的收缩压、舒张压及动脉压均存在差异有统计意义(P<0.05)。结论在室上性宽QRS心动过速诊断中应用Brugada四步诊断法有重大价值。
Objective To systematically analyze the clinical diagnosis and characteristics of wide QRS complex tachycardia. Methods The clinical data of 85 patients with supraventricular wide QRS tachycardia diagnosed and treated in our hospital were retrospectively analyzed. The 12-lead body surface electrocardiogram was performed. At the same time, Brugada four-step diagnosis and ventricular tachycardia were used to analyze and summarize the clinical features, blood Flow mechanics and ECG and so on. Results Among the 85 patients in this group, 78 were diagnosed as supraventricular tachycardia with bundle branch block or ventricular differential conduction with a specificity of 91.8% and a sensitivity of 100%. According to ventricular rate analysis, <180bpm patients and> 180bpm patients Systolic blood pressure, diastolic blood pressure and arterial pressure were statistically significant differences (P <0.05). Conclusion The application of Brugada four-step diagnostic method in the diagnosis of supraventricular QRS tachycardia is of great value.
