-
Classic Wolff-Parkinson-White electrocardiogram with short PR, QRS >120 ms, and delta wave.
-
Preexcited atrial fibrillation.
-
Variants of Wolff-Parkinson-White syndrome (unusual accessory pathways).
-
Accessory pathway potential and local AV fusion at successful RF ablation site with loss of preexcitation and return of normal HV interval.
-
Electrocardiogram of asymptomatic 17-year-old male who was incidentally discovered to have Wolff-Parkinson-White pattern. It shows sinus rhythm with evident preexcitation. To locate accessory pathway (AP), initial 40 ms of QRS (delta wave) is evaluated. Note that delta wave is positive in I and aVL, negative in III and aVF, isoelectric in V1, and positive in rest of precordial leads. Therefore, this is likely posteroseptal AP.
-
12-lead electrocardiogram from asymptomatic 7-year-old boy with Wolff-Parkinson-White pattern. Delta waves are positive in I and aVL; negative in II, III, and aVF; isoelectric in V1; and positive in rest of precordial leads. This predicts posteroseptal location for accessory pathway.
-
12-lead electrocardiogram showing short PR interval and delta waves consistent with presence of accessory pathway.
