ANATOMY OF THE ATRIOVENTRICULAR NODE AND ATRIOVENTRICULAR CONDUCTION SYSTEM
International Journal of Bifurcation and Chaos, 2003The anatomy of the atrioventricular conduction system was first described nearly a hundred years ago. Since then, it has been an occasional subject of controversy mainly through a lack of adherence to the original definitions based on histology. The gross landmarks for locating the atrial component of the conduction system are found in the right ...

Journal of the American Society of Echocardiography, 2019
In patients with structurally normal atrioventricular valvular apparatus, functional regurgitation of the mitral or tricuspid valves has been attributed mainly to ventricular dilation and/or dysfunction, through a combination of annulus dilation and ...

Atrioventricular block and problems with atrioventricular conduction
Clinics in Geriatric Medicine, 2002This chapter has summarized briefly the current state of our knowledge on the incidence, etiology, presentation, investigation, and management of patients with AV block. The scope of the material covered has been widened intentionally to include a plethora of AV-conduction abnormalities because of the increases in the understanding of their clinical ...

Atrioventricular Block in an Infant With an Atrioventricular Septal Aneurysm
Pediatric Cardiology, 2011A case of atrioventricular (AV) septal aneurysm presenting in late fetal life with AV block is reported. In the neonatal period, second-degree AV block occurred, which progressed during infancy to complete block. This report includes ante- and postnatal echocardiograms demonstrating the anatomy.

Atrioventricular nodal Reentrant Tachycardia with Atrioventricular Block
Journal of Interventional Cardiac Electrophysiology, 1997Atrioventricular block (AVB) during atrioventricular nodal reentrant tachycardia (AVNRT) has been well documented, although it is not a common phenomenon. The mechanism for the initiation and resolution of AVB during AVNRT have been postulated. However, the site of AVB and its implication on the reentrant circuit in AVNRT is not clear.

Atrioventricular Block and Atrioventricular Dissociation
2004Atrioventricular (AV) block is not only linked to some important electropathophysiologic mechanisms such as conduction slowing and escape rhythm, but also to typical ECG patterns such as Wenckebach period or Mobitz block, and to other potential precursors of complete AV block such as fascicular blocks and their combinations. All in all, AV block in its

AACN Advanced Critical Care, 1992
The presentation of atrioventricular block in the critical care setting and the assessment parameters that the critical care nurse may use to aid in the determination of the severity of atrioventricular block are described. The underlying pathophysiology of atrioventricular block is examined to enhance the nurse’s understanding of the rationale for ...

Atrioventricular block after reciprocating atrioventricular junctional tachycardia
The American Journal of Cardiology, 1975Short runs of symptomatic atrioventricular (A-V) block occurred after spontaneous cessation of reciprocating A-V junctional tachycardia in a patient with right bundle branch block, normal H-V interval and sinus nodal dysfunction. These episodes were characterized by long (more than 1 sec) P-P intervals during which the A deflections were not followed ...

Clarifying the anatomy of the atrioventricular node artery.
International Journal of Cardiology, 2018BACKGROUND Reports of conduction abnormalities necessitating permanent pacemaker implantation due to atrioventricular node artery injury and increasing evidence of stenosis of the atrioventricular node artery in cases of sudden death are of unsolved ...

Anatomy of the Atrioventricular Junction, Atrioventricular Grooves, and Accessory Pathways
Cardiac Electrophysiology Clinics, 2020Accessory pathways that bypass all or part of the normal atrioventricular conduction system traverse the atrioventricular junction. The atrioventricular junction comprises of a limited septal component and much more extensive right and left parietal components.
