目的 评价碎裂QRS波(fQRS波)在致心律失常性右心室心肌病(ARVC)诊断中的价值.方法 43例符合ARVC诊断标准的患者,男性33例,平均年龄(40.4±13.9)岁.采集临床资料,记录静息状态下标准12导联心电图,描述fQRS波的心电图特征,判断是否存在fQRS波、epsilon波和右胸前导联T波倒置(TWI)并比较其阳性率之间的差异.结果 本组患者fQRS波以下壁导联(44.3%)和右胸前导联(24.2%)最为多见.QRS波中,fQRS波见于R波者多于S波者(58.4%对32.9%,Z=4.30,P＜0.01).共31例患者判断为fQRS波阳性,2～9(4.6±1.7)个/例.fQRS波阳性率较epsilon波(73.8%vs 30.2%,Z=3.67,P＜0.01)和TWI(73.8%对41.9%,Z=2.61,P＜0.01)显著增高.结论 fQRS波阳性是ARVC患者常见的心电图异常,常见于下壁和右胸前导联,可作为提示诊断的无创心电指标.

Objective To evaluate diagnostic value of fragmented QRS complex (fQRS)in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). Methods Forty-three patients [33 men, aged (40. 4 ± 13.9)years]meet the ISFC/ESC diagnostic criteria for ARVC were enrolled in this study. A standard twelve-lead electrocardiogram was obtained during the resting status. Characteristics of fQRS were detailedly studied by three doctors independently. A comparison of the prevalence among fQRS, epsilon wave and T wave inversion( TWI )in the right precordial leads exceeding V3 was done. Results Most fQRS could be found in the inferior leads (44. 3% ) and the right precordial leads (24. 2% ). Within the QRS complex, the prevalence of fQRS in the R wave was significantly higher than it in the S wave(58. 4% vs 32. 9% ,Z =4. 30,P ＜0. 01 ).fQRS could be found in a total of 31 of 43 cases( mean 4. 6 ± 1.7 ( range 2 to 9) per patient). The prevalence of fQRS was significantly higher than that of epsilon wave ( 73.8% vs 30. 2%, Z = 3.67, P ＜ 0. 01 ) and TWI (73.8% vs41.9% ,Z =2. 61 ,P＜0. 01 ). Conclusion fQRS was a common electrocardiographic abnormality,and most was found in the inferior and right precardial leads in patients with ARVC. It may be used as an important noninvasive preliminary screening electrocardiographic criteria.
