WebbECG characteristics of early repolarization The ST segment elevations are concave and most pronounced in the chest leads. T-waves have high amplitude. The hallmark of early repolarization is the end-QRS slurring or end-QRS notching (both may occur on the same ECG). The entire notch must be above the baseline. Webb16 juni 2024 · The surface ECG in an asymptomatic person is widely used to detect WPW syndrome. It appears as a delta wave, a slurred upstroke in the QRS complex accompanied by a brief PR interval. If the patient has atrial fibrillation, the ECG will indicate fast polymorphic wide-complex tachycardia (without turning points). can owl see in daylight
