A few words of thanks would be greatly appreciated.

Junctional tachycardia - Definition


Junctional tachycardia is an acceleration of the heart rate caused by neither the atria nor the ventricles of the heart, but by a node responsible for the spread of electrical impulses in the heart, called the atrioventricular node. This condition manifests as an accelerated heart rate, with sudden on-set palpitations, and particularly affects children. This is a one-off condition which resolves by itself. It cannot be revealed by electrocardiogram, unless performed during an episode. There are medicinal treatments available based on striadyne, or adenosine triphosphate, or therapies focused on what are called vagal manoeuvers aimed at stopping the junctional tachycardia when it strikes. General background treatment consists of medication that slows the heart rate (beta-blockers) or antiarrhythmic agents.
