ABSTRACT
Objective:
To explore the effects of cardiac resynchronization therapy (CRT) in patients with dispersion of re-polarization and ventricular arrhythmia.Methods:
A total of 86 consecutive patents with CRT implantation were enrolled. According to weather absolute value of LVEF increased≥10% from baseline at 6 months after CRT implantation, the patients were divided into 2 groups Response group and Non-response group,n=43 in each group. Dispersion of re-polarization indexes as QRS duration, QTc interval, TpTe interval and the events of ventricular arrhythmia were compared between 2 groups at different time points after CRT.Results:
①In Response group, compared with pre-operation, QRS duration and TpTe interval were shorter at 1 year and within 24h after CRT implantation, allP0.05.②During 1 year after CRT implantation, the incidences of PVCs and PVC runs in Response group were much less than those in Non-response group, for lgPVCs (1.78 ± 0.77) vs (2.73 ± 0.61), for lgPVC runs (0.64 ± 0.48) vs (1.98 ± 0.72),PConclusion:
CRT ventricular reverse remodeling may reduce dispersion of re-polarization and the risk of ventricular arrhythmia, therefore improve the prognosis in relevant patients; TpTe interval within 24h after CRT had the predictive value for ventricular arrhythmia.
