Treatment of PMT typically involves reprogramming the pacemaker. [46] Another possible complication is "pacemaker-tracked tachycardia," where a supraventricular tachycardia such as atrial fibrillation or atrial flutter is tracked by the pacemaker and produces beats from a ventricular lead. [47]
Treatment is rarely required because, in most cases, it is asymptomatic. If symptoms develop, medication can be pursued for symptomatic relief. In the setting of suspected sinus node dysfunction manifesting as wandering atrial pacemaker, evaluation for pacemaker placement may be done due to sinus node damage. [2]
Similar high rates of success are achieved with AVRT and typical atrial flutter. [25] Cryoablation is a newer treatment involving the AV node directly. SVT involving the AV node is often a contraindication to using radiofrequency ablation due to the small (1%) incidence of injuring the AV node, then requiring a permanent pacemaker.
Since pacemaker correction of the third-degree block requires full-time pacing of the ventricles, a potential side effect is pacemaker syndrome, and may necessitate the use of a biventricular pacemaker, which has an additional 3rd lead placed in a vein in the left ventricle, providing more coordinated pacing of both ventricles.

An ectopic pacemaker located in the atria is known as an atrial pacemaker and can cause the atrial contraction to be faster. [10] An ectopic pacemaker situated near the AV node and the septum is known as a junctional pacemaker. [11] The pacemaker that is operating in the ventricles is known as the ventricular. [12]
[5] [7] [8] The goal of this treatment modality is to relieve symptoms associated with sinus node dysfunction and improve quality of life. [5] Dual chamber pacemakers are preferred due to the possibility of developing atrioventricular block [5] as well as long term cost-effectiveness relative to single-chamber atrial pacemakers. [9]
