PMT and Upper Rate Behavior Exam questions and answers Graded A+ latest update Pacemaker Mediated Tachycardia - Endless-loop tachycardia sustained by the presence of the dual chamber pacemaker. The pacemaker is sensing and tracking retrograde conduction, which causes inappropriately fast pacing. Conditions Necessary for Reentrant Tachycardia - 1) Circuit with 2 limbs of different conduction times and therefore different recovery/refractory times 2) Triggering Event (Desynchronizing Event) 3) Block along one pathway that allows conduction down the other (unidirectional block) 4) Recovery of the blocked pathway allowing for reentry back up the recovered pathway Are all patients capable of having PMT? - No What are the requirements for Pacemaker Mediated Tachycardia (PMT)? - 1) Dual Chamber device in tra
