Figure Lengend Snippet: Graphs show associations between LV left ventricle diffuse fibrosis and ECG electrocardiography parameters in the LGE late gadolinium enhancement-negative group—namely, the relationships of (a) postcontrast T1 time and (b) ECV extracellular volume fraction to QRS voltage, QRS duration, and QTc corrected QT interval. Note that greater diffuse fibrosis manifested as shorter postcontrast T1 time and that greater ECV extracellular volume fraction was associated with lower QRS voltage and shorter QRS duration but was not associated with QTc corrected QT interval. Dashed lines = 95% confidence intervals.
Article Snippet: ECG Measurements Surface ECG electrocardiography studies were performed digitally at 10 mm/mV calibration and a speed of 25 mm/sec by using MAC 1200 ECG electrocardiography machines (Marquette Electronics, Milwaukee, Wis) in all clinical centers.
