RESUMO
Pacemaker-mediated tachycardia (PMT) is an arrhythmia seen in patients implanted with dual-chamber pacemakers. It occurs when ventricular contraction is followed by retrograde conduction to the atrium; which is sensed by the pacemaker; leading to ventricular triggering. A vicious re-entry cycle is set up; leading to incessant tachycardia unless appropriately terminated. A common precipitant is a premature ventricular contraction (PVC). Although PVCs are frequently generated during ventriculography; PMT is an extremely rare event during cardiac catheterisation despite the fact that a large number of patients with implanted pacemakers do undergo the procedure. We report on a case and hope to highlight the possibility of PMT occurring during catheterisation; as well on therapeutic options
