【摘要】 目的探讨室速积分法与其他室速诊断流程鉴别预激性心动过速的临床价值。方法选取31例经过心内电生理检查确诊预激性心动过速的患者,分析其发作时的12导联心电图,用室速积分法对预激性心动过速进行评分,并以积分值2分作为对照组,对比分析Brugada、Wellens和Vereckei等流程诊断预激性心动过速的特异性差异。结果 (1)31例患者中,室速积分法≥3分诊断预激性心动过速的患者为0例,特异度为100%;(2)室速积分法2分与Brugada、Wellens和Vereckei等流程法的结果对比,诊断预激性心动过速的特异度分别为77.4%、48.4%、22.6%和19.4%,差异有统计学意义(均为P<0.05)。结论室速积分法≥3分可鉴别预激性心动过速与室性心动过速。室速积分法2分不能完全区分预激性心动过速与室性心动过速,但特异性明显优于Brugada、Wellens和Vereckei等流程法。更多还原

【Abstract】 Objective To investigate the clinical value of ventricular tachycardia(VT)score and other VT diagnostic algorithms in identifying pre-excited tachycardia. Methods Twelve-lead electrocardiograph results were obtained from 31 patients at pre-excited tachycardia attacking stage who were diagnosed by electrophysiology. First, we scored pre-excited tachycardia based on the VT score. Then, taking the VT score of 2 points as the control group, the specificity of Brugada, Wellens and Vereckei algorithms in diagnosing pre-excited tachycardia were compared and analyzed. Results(1) The diagnostic value of VT score for patients with pre-excited tachycardia(≥ 3 points) was 0, the specificity was 100%.(2) Comparing the results of the VT score 2 point with those of Brugada, Wellens, and Vereckei algorithms, the specificities were 77.4%, 48.4%, 22.6% and 19.4% respectively, the differences were statistical significantly(all P<0.05). Conclusions VT score ≥3 points can completely identify pre-excited tachycardia and VT. Score of 2 points cannot completely distinguish pre-excited tachycardia from VT, but its specificity is obviously better than of Brugada, Wellens and Vereckei algorithms.更多还原
