The clinical study of relationship among different bundle bronch conduction with Doppler echocardiography ventricular arrhythmia in dilated cardiomyopathy
Abstract：Objective To study the relationship among different bundle bronch conduction with Doppler echocardiography,ventricular arrhythmia(VA) and other clinical materials in dilated cardiomyopathy(DCM).Methods 140 patients were divided into five groups according to different bundle bronch conduction in 12-leads electrocardiograme(groups CLBBB,CRBBB,CRBBB+LAFB,LAFB and normal bundle bronch conduction NBBC).By receivel clinical materials and measured parameters of Doppler echocardiography,24 hours ambulatory electrocardiograme before drug treatment in every group.The correlation between these data were assessed.Results Using statistic analyses showed that among different bundle bronch conduction groups in patients with DCM,the sick duration,the NYHA functional class,the heart thorax ratio,ther LV end-diastotic and end -systolic volume,the LV ejection fraction,the peak E velocity,E/A ratio and above I owns Ⅱ degree VA in groups CLBBB,CRBBB,CRBBB+LAFB were more serious than those in groups LAFB and NBBC.Conclusion Our data provide relevant information among different bundle bronch conduction groups,CLBBB、 CRBBB and CRBBB+LAFB are associated with the risk parameters of Doppler echocardiography,ventricular arrhythmia.
