The main symptom of AVNRT is the sudden development of rapid regular palpitations. [1] These palpitations may be associated with a fluttering sensation in the neck, caused by near-simultaneous contraction of the atria and ventricles against a closed tricuspid valve leading to the pressure or atrial contraction being transmitted backwards into the venous system. [2]
Atrial flutter is also not necessarily a tachycardia by definition unless the AV node permits a ventricular response greater than 100 beats per minute. AV nodal reentrant tachycardia (AVNRT) involves a reentry circuit forming next to, or within, the AV node. The circuit most often involves two tiny pathways one faster than the other.
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]

Type I atrial flutter, counterclockwise rotation with 3:1 and 4:1 AV nodal block. Atrial flutter with a two to one block. Note the P waves hiding in the T waves in leads V1 and V2. Type I atrial flutter, also known as common atrial flutter or typical atrial flutter, has an atrial rate of 240 to 340 beats/minute.
Research suggests that this leadership style can reduce job satisfaction and engagement, making employees feel less connected to the organization and more likely to leave. While it may effectively achieve short-term goals, the lack of collaboration can create a workplace environment where employees feel undervalued or overly controlled.
In the Dilbert comic strip of February 5, 1995, Dogbert says that "leadership is nature's way of removing morons from the productive flow". Adams himself explained, [1] I wrote The Dilbert Principle around the concept that in many cases the least competent, least smart people are promoted, simply because they’re the ones you don't want doing actual work.
The Functional theory of leadership emphasizes how an organization or task is being led rather than who has been formally assigned a leadership role. In the functional leadership model, leadership does not rest with one person but rests on a set of behaviors by the group that gets things done. Any group member can perform these behaviors so ...
