摘　　要：目的:研究全皮下置入式心律转复除颤器(S-ICD)术前心电图QRS-T形态模板匹配筛查(TMS)对于双室起搏患者反应性的预测价值。方法:2016年1月至2017年3月,中国医学科学院阜外医院心脏再同步化治疗CRT(CRT-P/CRTD)置入的患者共55例,利用TMS对患者在心脏再同步化治疗(CRT)置入术前和术后进行S-ICD两种体位三个向量下的心电图描记和筛查,统计TMS通过率。在CRT置入后第6个月对患者进行随访,对比TMS通过与未通过患者的CRT的反应率。结果:所有患者在CRT置入术前,自身心律时均未通过TMS筛查,39例患者(70.9%)在双室起搏状态下通过TMS筛查。TMS通过组中高血压患者的比例低于TMS未通过组(7.7%vs.43.8%,P=0.004)。6个月随访时,TMS通过组有反应和超反应的患者比例明显高于未通过组(有反应:31/36(86.1%)vs.5/16(31.3%),P<0.001;超反应:9/39(23.1%)vs.1/16(6.3%),P=0.026)。三个向量均通过的患者超反应比率高于另外两组(3向量vs.2向量,P=0.018;3向量vs.1向量,P=0.003)。基线时较小的LVEDD、LAD以及双室起搏通过TMS筛查是CRT有反应的预测因素。结论:双室起搏模式下通过TMS的患者CRT置入后更易有反应及超反应。Objective： We aimed to investigate the electrocardiogram（ QRS-T morphology） of the biventricular pacing patients using the subcutaneous implantable cardioverter defibrillator pre-implantable QRST morphology screening（ TMS） and the predictive value of TMS for CRT response. Methods： From January2016 to March 2017,55 patients were implanted with Cardiac Resynchronization therapy/defibrillator（ CRT-P/CRTD） in Fuwai Hospital,TMS was conducted before and after implantation using an ECG simulating the 3 sensing vectors of the S-ICD. Patients were followed up at the 6 month after CRT implantation to record the response of the CRT. Results： 39 patients（ 70. 9%） passed TMS in Biventricular pacing mode while all patients failed to pass the TMS under the intrinsic rhythm. Compared with the non-pass group,the proportion of patients with hypertension in the Biventricular pass group was lower（ 7. 7% vs. 43. 8%,P = 0. 004） At the 6 months follow-up,both the two groups improved significantly in the cardiac function. 36 patients were defined as responders to CRT,10 were super responders. More responders and super responders were observed in biventricular pass group than those in the non-pass group（ response： 31/36（ 86. 1%） vs. 5/16（ 31. 3%）,P〈0. 001; super response： 9/39（ 23. 1%） vs. 1/16（ 6. 3%）,P = 0. 026） The ratio of super responders in those patients who passed TMS with all three vectors was higher than that of the other two groups（ 3 vector vs. 2 vector,P =0. 018; 3 vector vs. 1 vector,P = 0. 003） Smaller baseline LVEDD,LAD,and TMS pass during the biventricular pacing mode were independent predictors of CRT response. Conclusion： The CRT patients who passed the TMS during the biventricular pacing mode are more susceptible to respond to CRT.
