Pacemaker-mediated
tachycardia(PMT) is a circus movement tachycardia that can occor in patients with
dual chamber pacemaker with atrial sensing (VDD or DDD), when a ventricular depolarization,
either spontaneous or paced, causes retrograde activation of the atrium. Recently,
a number of pacemaker manufactures have incorporated in their devices a variety
of relatively complex algorithms to prevent PMT. Despite these measures, PMT may
still occur because of inappropriate programming or unpredictable variations of
ventriculoatrial conduction.
We
report one case of PMT in a 78-year-old male who received DDD type pacemaker due
to sick sinus syndrome. In this case, PMT was disappeared after reprogramming parameters
of pacemaker and the application of PMT protection algorithm. |
