The prognostic effects of tachycarrhythmias in patients with dilated cardiomyopathy

目的 探讨快速性心律失常 ( TCA)对扩张型心肌病 ( DCM)患者预后的影响。方法 对 4 2例 DCM伴 TCA患者 ,住院期间是否发生死亡 ,分为死亡组与存活组 ,分析两组临床特征及心电图。结果 死亡组室性心动过速 ( VT)发作频率快、阵数高、多形性 VT的发生率高 ( P <0 .0 5～ 0 .0 0 1) ;死亡组左心室射血分数 ( L VEF)明显低于存活组 ( P <0 .0 0 1)。结论 DCM伴 VT,具有发作频率快、阵数高、多形性 VT的特点 ,是

Objective To explore the prognostic effects of tachyarrhthmias in patients with dilated cardiomyopathy. Methods 42 patients were included in the stude(12 patients cardiac death, 30 patients survivor)with DCM and TCA, and clincal features and electrocardigraphy were analyzed. Results The higher episodes in holter, the more beats in episodes, the faster ventricular rate, the long duration of QRS complex wave of VT in cardiac death group were observed than those in survivor group(P<0.05~0.001). The left ventricular ejection fraction was lower in cardiac death group than those in survivor group(P<0.001). Conclusion The DCM with the more beats in episodes, the faster rate, the higher episodes, the long duration of QRS complex wave of VT detected by 24-hour holter monitoring are high risks of sudden death.
