Ubicación inesperada del electrodo marcapasos: ¿es correcto?

Abstract

A 74-year-old woman presented with weakness, dizziness, dyspnea, and chest pain. A 2nd degree atrioventricular block was found. Transvenous temporary pacemaker (TTP) was implanted. Post-TTP implantation electrocardiography (ECG) showed a paced rhythm with a right branch block (RBBB) morphology, inconsistent with the right ventricular stimulation – as expected for this type of device.
