Prognostic markers derived from standard ECG have always been seductive.Increased dispersion of durations of the P wave, of the QRS complex, or of the QT interval has been associated with the risk of atrial fibrillation, ventricular Decorative Bowls arrhythmias, sudden cardiac death, as well as with a general negative prognosis in various settings.
