Tachycardia1
This can lead to an Atrioventricular reentrant tachycardia which may pass anterogradely or retrogradely through the AV node and accessory pathway. (abcmedicalnotes.com)
HN - 2008 BX - Lateral Sinus MH - Atrial Septum UI - D054087 MN - A07.541.459.249 MS - The thin membrane-like muscular structure separating the right and the left upper chambers (HEART ATRIA) of a heart. (bvsalud.org)
Bypass tract1
An accessory "bypass tract" can avoid the AV node and its protection so that the fast rate may be directly transmitted to the ventricles. (wikipedia.org)
Supraventricular1
The main pumping chamber, the ventricle, is protected (to a certain extent) against excessively high rates arising from the supraventricular areas by a "gating mechanism" at the atrioventricular node, which allows only a proportion of the fast impulses to pass through to the ventricles. (wikipedia.org)
Abnormal1
WPW - there is an abnormal electrical connection between atrium and ventricle (e.g. bundle of Kent) - this is called an accessory pathway. (abcmedicalnotes.com)
Node1
Second-degree atrioventricular (AV) block, or second-degree heart block, is characterized by disturbance, delay, or interruption of atrial impulse conduction through the AV node to the ventricles. (medscape.com)
Block1
Back in November 2019 Medtronic announced results from the MARVEL 2 (Micra Atrial Tracking Using A Ventricular accELerometer) study showing that an investigational set of algorithms in the Micra™ leadless pacemaker improves synchrony and cardiac function in patients with atrioventricular (AV) block.

Types1
May be an RSR pattern in V1 with Type A however there are several different types depending on location of accessory pathway. (abcmedicalnotes.com)
Nodal reentrant tachycardia2
[1] Examples of SVT include atrial flutter, atrial fibrillation (AF), atrioventricular nodal reentrant tachycardia (AVNRT), also known as paroxysmal supraventricular tachycardia (PSVT), atrioventricular reentrant tachycardia (AVRT), and multifocal atrial tachycardia (MAT). (nih.gov)
Atrioventricular Nodal Reentrant Tachycardia is a type of supraventricular tachycardia (ie it originates above the level of the Bundle of His) and is the commonest cause of palpitations in patients with hearts exhibiting no structurally abnormality. (crashingpatient.com)
Pathways1
The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias. (lookformedical.com)

Left1
Left atrial (LA) structures, including the accessory left atrial appendage (aLAA) and left atrial diverticulum, have been studied based on their prevalence, shape, and association with arrhythmia and thrombi formation. (researchgate.net)
