PMT Full Form in Medical

What is The Full Form of PMT?

PMT Full Form in Medical term is Pacemaker-Mediated Tachycardia. It is a situation where a pacemaker pace the ventricles at abnormally fast rates is known as pacemaker-mediated tachycardia (PMT). This may occur because

• The rate response setting is too sensitive
• The pacemaker is tracking atrial noise
• The pacemaker is being inappropriately manipulated while rate response is activated
• or the pacemaker is tracking an atrial tachyarrhythmia linked to upper rate settings.

However, pacemaker-mediated tachycardia, also known as endless-loop tachycardia, is commonly used to describe a type of reentrant tachycardia that can develop in individuals with dual-chamber pacemakers. The pacemaker is part of the circuit’s anterograde limb (from atrium to ventricle; A V), while the AV node is part of the retrograde limb (from ventricle to atrium; V A).

Individuals with the dual pacemakers are more likely to experience pacemaker-mediated tachycardia, an arrhythmia caused by reentry.

Symptoms

Patients with this arrhythmia often experience lightheadedness, dizziness, and fainting. Resetting the pacemaker’s settings to lengthen the atrial recovery time is a cornerstone of treatment. Pacemaker-mediated tachycardia is discussed in detail, as is the evaluation and therapy of this problem, with a focus on the involvement of the interdisciplinary team in the patient’s overall care.
