【摘要】：本文報道了1例診斷為擴張型心肌病的患者,通過雙腔起搏器單左心室起搏運用頻率適應(yīng)性房室延遲(RAAV)功能實現(xiàn)心臟再同步化治療(CRT)。通過術(shù)后6個月隨訪,QRS波時限由術(shù)前170 ms變窄為術(shù)后118 ms,左心室舒張末內(nèi)徑(LVDd)由術(shù)前78 mm縮小為術(shù)后49 mm,左心室射血分數(shù)(LVEF)由術(shù)前32%升高為術(shù)后48%,心胸比由術(shù)前0.64減小為術(shù)后0.55,美國紐約心臟病學會(NYHA)心功能分級由術(shù)前Ⅲ級降低為術(shù)后Ⅰ級,左房室瓣反流面積(MRA)由術(shù)前14.0 cm~2減少為術(shù)后1.8 cm~2,左心室12節(jié)段達峰時間標準差(TS-SD12)由術(shù)前150 ms減少為術(shù)后77 ms,主、肺動脈射血時間差(IVMD)由術(shù)前47 ms改善為術(shù)后33 ms,達到超應(yīng)答標準。同時結(jié)合文獻復習,以提高臨床醫(yī)生對雙腔起搏器通過RAAV實現(xiàn)雙室收縮再同步的認識和應(yīng)用。
[Abstract]:A patient with dilated cardiomyopathy (DCM) was treated with (CRT). By double chamber pacemaker and single left ventricular pacing with frequency adaptive atrioventricular delay (RAAV) function. After 6 months follow-up, QRS wave duration narrowed from 170ms before operation to 118ms, left ventricular end-diastolic diameter (LVDd) decreased from 78mm to 49mm, left ventricular ejection fraction (LVEF) increased from 32% before operation to 48 mm postoperatively, cardiothoracic ratio increased from pre-operation to post-operation. The (NYHA) cardiac function grade of the New York College of Cardiology was reduced from preoperative grade 鈪，
