The purpose of this article is to analyze a clinical case pacemaker-mediated tachycardia. It can develop only in patients with dual-chamber or biventricular pacemakers and preserved ventriculoatrial conduction. mechanism tachycardia re-entry between pacemaker conduction system. A thorough examination patient, Holter ECG monitoring, interrogation are the main strategic approaches for correctly diagnosing PMT differentiating it from other types arrhythmias. To prevent occurrence PMT, necessary be familiar antitachycardia algorithms various models. primarily recommended always activate automatic detection elimination which usually sufficient proper functioning device. If necessary, additional measures such as reprogramming postventricular atrial refractory period AV delay should considered. With appropriate programming, recurrences mostly avoided. long-term prognosis favorable.
