SCREENIG OF LEFT VENTRICULAR FUNCTION BY SIGNAL-AVERAGED ELECTROCARDIOGRAM

摘要

We clarified the relationship between left ventricular function and the parameters of signal-averaged electrocardiograms (SAE). A significant correlation was observed between the parameters in the time domain analysis and the LVEF. Particularly, Total root mean square voltageRMS (TRMS) revealed good correlation (r=0.40, p=0.0001). Filtered QRS was significantly longer (p=0.002), and TRMS was significantly lower (p=0.0001) in the group with low EF (<0.35) vs. high EF (> 0.35). The parameters of SAE correlate with the left ventricular ejection traction. Particulary, TRMS is a favorable parameter for screening of cardiac function
