*
GIII values significantly different from those of other groups
#
GII values significantly different from CG values
CG: control group; GI: indeterminate form; GII: electrocardiographic abnormalities and LV ejection fraction ≥ 0.55; GIII: electrocardiographic abnormalities and LV ejection fraction < 0.55; LVDD: left ventricular diastolic diameter; LAVmax: maximum left atrial volume; LAVpre P: pre-P-wave left atrial volume; LAVmin: minimum left atrial volume.
