摘要
目的:探讨缺血性心肌病(ICM)患者左心室重构和心功能与室性心律失常的关系。方法:120例ICM患者分别按左心功能和左心室舒张末期内径(left ventricle end diastolic dimension,LVEDd)分组,分析各组患者发生室性心律失常的情况。结果:ICM患者的复杂型室性早搏、室内传导阻滞、室性早搏并发室内传导阻滞的发生率与LVEDd有明显相关性,差异有显著性(P<0.05);复杂型室性早搏的发生率与左心功能有关,差异有显著性(P<0.05),而室内传导阻滞以及室性早搏并发室内传导阻滞的发生率与左心功能无关,差异无显著性(P>0.05);简单型室性早搏的发生率与LVEDd和左心功能无关,差异无显著性(P>0.05)。结论:ICM患者复杂型室性早搏发生与LVEDd及心功能有明显相关性,LVEDd重度增大者更易发生室性早搏及室内传导阻滞。
Objective： To investigate the relationship of left ventricular remodeling and cardiac func- tion with ventricular arrhythmias in patients with ischemic cardiomyopathy （ICM）. Methods： Total 120 cases with ICM were divided into groups according to left ventricle end-diastolic dimension （LVEDd） and left ventricular function, and the occurrence of ventricular arrhythmias in each group was investigated. Results： The occurrence of complex ventricular premature beat, intraventricular block and ventricular premature beat complicated with intraventricular block was related to LVEDd （P 〈 0. 05 ） ; the occurrence of complex ventricular premature beat was related to left heart function （ P 〈 0. 05）, while intraventricular block and ventricular premature beat complicated with intraventricular block was not related to left heart function （P 〉 0. 05 ）. Simple type of ventricular premature beat was not related to LVEDd and left heart function （ P 〉 0. 05 ）. Conclusions： The occurrence of complex ventricular premature beat is related to LVEDd and left heart function. When LVEDd is severe enlarge- ment, ventricular premature beat complicated with intraventricular block is more likely to occur.
