PACEMAKER MEDIATED TACHYCARDIA is a term for several different mechanisms that cause inappropriately fast rates in a paced patient. It is a very interesting topic, which I will not attempt to discuss here, because it has been done to perfection by DR. KEN GRAUER, MD, with assistance from JASON ROEDIGER, CCT, CRAT in Dr. Grauer's ECG Consult #13 Please follow this link to a concise, complete, and illustrated discussion of PMT.
Do you ever feel confused by pacemaker rhythms? You are not alone! Pacemakers are electronic devices, and have rapidly evolved in their capabilities. Often, we call the manufacturer's representative to come and interrogate a patient's pacemaker to determine if it is behaving as it was programmed. Without knowing the programming of the individual pacemaker, it can be hard to evaluate the patient's rhythm.
