This is the property of the AV node that prevents rapid conduction to the ventricle in cases of rapid atrial rhythms, such as atrial fibrillation or atrial flutter. The AV node's normal intrinsic firing rate without stimulation (such as that from the SA node) is 40–60 times/minute. [ 13 ]
During typical AVNRT, electrical impulses travel down the slow pathway of the AV node and back up the fast pathway. The fundamental mechanism of AVNRT is a presence of a dual atrioventricular node physiology (present in half of the population), which acts as a re-entrant circuit within the atrioventricular node. [4] This can take several forms.
An automatic tachycardia is a cardiac arrhythmia which involves an area of the heart generating an abnormally fast rhythm, sometimes also called enhanced automaticity.These tachycardias, or fast heart rhythms, differ from reentrant tachycardias (AVRT and AVNRT) in which there is an abnormal electrical pathway which gives rise to the pathology.

The Journal of Labor Research is a peer-reviewed academic journal which publishes articles regarding labor relations in the United States. Its articles cover the nature of work, labor-management relations, welfare-to-work, flexible employment, labor policy, regulation of labor unions, dispute resolution, and workplace grievance resolution.
Junctional tachycardia is a form of supraventricular tachycardia characterized by involvement of the AV node. [1] It can be contrasted to atrial tachycardia.It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node due to an A-V disassociation. [2]
The journal was founded as the Hofstra Labor Law Journal in 1982. It publishes articles on labor law and employment relations, covering issues such as the National Labor Relations Act, employment discrimination, termination, sexual harassment, the Americans With Disabilities Act, work for hire, whistleblower and retaliatory discharge, workplace ...
