BARANCHUK, Adrián; RIBAS, Sebastián; DIVAKARAMENON, Syamkumar  and  MORILLO, Carlos A.. Real time intracardiac electrograms for the diagnosis of pacemaker malfunction. Medicina (B. Aires) [online]. 2008, vol.68, n.1, pp.62-64. ISSN 0025-7680.

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.

Keywords : Pacemaker malfunction; Electrograms; Lead dislodgement.
