Pacemaker mediated tachycardia

Pacemaker mediated tachycardia is an arrhythmia where a re-entrant loop through the AV node causes a retrograde P wave that is sensed as a native beat and used to trigger ventricular pacing. This causes a tachycardia at the maximum rate of the pacemaker. It is also known as endless-loop tachycardia or pacemaker circus movement tachycardia.
