Electrode causation of pacemaker inhibition.
Electromechanical nonphysiologic signals caused by the movement of intracardiac metal portions of an endocardial grasping electrode were shown to be "falsely" recycling an implanted pacemaker. The signals were similar in amplitude and slew rate to the ventricular electrogram and were terminated by ending the movement of the two metallic surfaces.
