右心室高位间隔联合右心房起搏治疗慢性充血陛心力衰竭的临床疗效观察

Clinical effect of right high-interventricuiar septal and atrial pacing to treat chronic congestive heart failure

目的观察右心室高位间隔联合右心房起搏治疗慢性充血性心力衰竭的临床疗效。方法10例慢性充血性心力衰竭患者，行右心室高位间隔联合右心房起搏治疗，于术前3d、术后3个月及6个月行心功能NYHA分级、6min步行距离、QRS波时限、左心室舒张末期内径（LVEDd）、LVEF及每搏量（SV）。结果右心室高位间隔联合右心房起搏后，心功能NYHA分级提高，6min步行距离增加，QRS波时限及LVEDd缩小，SV增加。结论右心室高位间隔联合右心房起搏治疗慢性充血性心力衰竭有一定的临床疗效。

Objective To observe the effect of right high-interventricular septal and atrial pacing to treat chronic congestive heart failure. Methods Ten chronic congestive heart failure patients received right high-interventricular septal and atrial pacing. Parameters was assessed, including New York Heart Association （NYHA） functional class,six-minute hall walk,the duration of QRS and left ventricular end-diastolic dimension （LVEDd）, LVEF, stroke volume （SV） before and after pacemakers implanted respectively. Resuits There was significant improvement of NYHA functional class,six-minute hall walk and SV after right high-interventricular septal and atrial pacing. The duration of QRS was shortened and LVEDd was decreased. Conclusion Right high-interventricular septal and atrial pacing could improve heart function in chronic congestive heart failure patients.
