宽QRS波群心动过速体表心电图的临床分析

A clinical analysis of wide QRS complex tachycardia on surface electrocardiogram

目的用Brugada的4步诊断法对宽QRS波群心动过速的心电网特点进行分析。方法选择住院或门诊符合QRS时间≥0．12s、频率〉100次／min的心动过速患者，分析常规12导联或18导联体表心电图。结果162例宽QRS波群心动过速患者，室上速91例，占56．17％，室速71例，占43．83％。结论Brugada法对宽QRS波群心动过速的鉴别诊断有重要意义，正确的诊断和及时的处理对患者至关重要。

Objective To analyze the electrocardiographic characteristics of wide QRS complex tachycardia by the Brugada four-step method. Methods The recordings of conventional 12- or 18-lead surface electrocardiogram were analyzed in the hospitalized or clinic tachycardia patients with QRS duration ≥ 0.12 s and frequency of 〉 100 heats/min. Results Of 162 patients with wide QRS complex tachycardia, 91 （ 56.17% ）were supraventrieular tachycardia and the remaining 71 （ 43.83% ）were ventricular tachycardia. Concluaions The Brugada four-step method is of important significance in the differential diagnosis of wide QRS complex tachycardia. Accurate diagnosis and timely treatment is vital for patients.
