| Popis: | In patients with manifest anterograde ventricular preexcitation, the electrocardiographic manifestation of the anomalous conduction through the simultaneous conduction over the atrioventricular (AV) node and the accessory pathway (“delta wave”); depends on several factors, the most representative being the conduction velocity over one or another connection. Occasionally, ventricular ectopic beats may present with retrograde penetration over one or both conduction pathways (AV node and/or accessory pathway), impacting on the morphology of the next immediate anterogradely conducted QRS. We present a case of a young patient with WPW syndrome and ectopic ventricular beats with different manifestations on the postectopic QRS due to concealed penetration of different conduction pathways. |
