Rechtsschenkelblock bei rechtsventrikulärer Stimulation

Abstract

Thus, it is suspected that malpositioning of the ECG electrodes generated an apparent RBBB morphology of the clinical tachycardia. Malpositioning of ECG electrodes switches the lead characteristics from horizontal (anterior-posterior) to frontal (cranial-caudal) plane properties. In this situation, the precordial leads V1 and V2 with positive vector in V1 and V2 imitate aVL (V2) and aVR (V1) and can produce an apparent RBBB morphology.
