RESUMEN
El desplazamiento crónico del catéter ventricular es una complicación infrecuente del implante de marcapasos. Es infrecuente que un catéter desplazado sense y capture en una cámara donde no fue implantado originalmente. Se presenta el caso de un paciente con marcapasos doble cámara en el que el catéter ventricular se desplazó hacia la aurícula derecha. El catéter desplazado permite sensar y capturar la aurícula. El diagnóstico inicial se realizó mediante el análisis deductivo conjunto de los electrogramas en tiempo real y los eventos en los canales de registro ("marker channel"). La radiografía de tórax confirmó el diagnóstico presuntivo.
ABSTRACT
Chronic ventricular lead dislodgement is an infrequent complication of pacemaker implantation. Occasionally, the dislodged lead may sense and capture a chamber in which the lead was not originally positioned. Intracardiac real time electrograms and channel markers are useful tools for the diagnosis of pacemaker malfunction. We present the case of a patient with a ventricular lead dislodgement into the atrium. The ventricular lead was able to sense and capture the atrium. Initial diagnosis was performed based on the deductive analysis of intracardiac real time electrograms and channel markers and confirmed by chest X-ray.
