摘要 患者男、78岁,因扩张型心肌病心衰、反复胸闷、气促5年,心衰加重1周再次人院。住院后患者的胸片提示双下肺纹理增粗,肺淤血,心胸比0.70;超声心动图提示:左室舒张末期内径73mm,射血分数32%,二尖瓣中等量返流,三尖瓣少量返流,室壁运动普遍性减弱;心电图表现为:窦性心律,完全性左束支阻滞,QRS时限190ms。经讨论,患者完全符合CRT治疗适应证,并于2008年6月26日植人心脏三腔起搏器。术后CRT主要以双心室起搏方式工作,优化程控vv间期为左室优先于右室30ms,心室后心房不应期(PVARP)275ms。心电图示窦性心律,双室同步起搏,QRS时限由术前190ms缩短为127ms。
