Clinical significance of high-frequency, low-amplitude electrocardiographic signals and QT dispersion in patients operated on for tetralogy of fallot

In conclusion, we found that in patients operated on for tetralogy of Fallot, signal-averaged electrocardiography is not useful for identifying patients at risk for severe ventricular arrhythmia, but the measurement of QT dispersion might be an appropriate noninvasive marker of electrical instabilit...
