Mapping in the atrioventricular junction [PDF]
Journal of Electrocardiology, 1991 Ectopic conduction is defined as the premature exit of the cardiac impulse from the specialized conduction system across a damaged Purkinje-ventricular muscle interface. This anomalous form of atrioventricular (AV) conduction was induced in the dog heart by lidocaine injection of the His bundle-interventricular septum interface and by ischemic damage ...

Septal Atrioventricular Junction Region: Comprehensive Imaging in Adults.
Radiographics, 2016The septal atrioventricular junction is a centrally located region of the heart where the septal components of the atria and ventricles meet the aortic, mitral, and tricuspid valves.

Atrioventricular Node Ablation [PDF]
Heart Failure Clinics, 2015 Cardiac resynchronization therapy (CRT) is a device-based, nonpharmacologic approach that has shown to improve the outcome in patients with heart failure in terms of mortality and morbidity reduction. Large randomized trials have virtually enrolled patients in New York Heart Association class III-IV, with reduced left ventricular ejection fraction ...

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 ...

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 nodal parasystole∗
The American Journal of Cardiology, 1964Abstract Ten cases of atrioventricular nodal parasystole have been discussed in detail. The variation of the shortest interectopic intervals was noted to be much greater than anticipated. The atrioventricular nodal parasystolic rate was somewhat slower than would be expected in view of the physiologic automaticity of the atrioventricular node; this ...

Atrioventricular Septal Defects (Atrioventricular Canal)
2015Partial atrioventricular (AV) canal is also known as ostium primum atrial septal defect (ASD) with a cleft or zone of apposition of the anterior leaflet of the left AV valve. Most anatomists and surgeons use the term “partial AV canal” for this entity, as it aligns with the other forms of AV canal and the ramifications of its repair are quite different

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.

Dual atrioventricular nodes [PDF]
Heart, 2014 To the Editor I read with great interest the ‘challenge’ posed by the electrocardiographic recording in issue 7 of Heart for 2014.1 I also noted with interest that the authors suggest that Monckeberg provided the first account of such dual nodes in 1993. Since Monckeberg was long since dead by that date, this must be some mistake!

Crossed atrioventricular connections
American Heart Journal, 1980Four cases of crossed atrioventricular connections are described. All of them were diagnosed at cardiac catheterization by angiocardiography and one was examined pathologically. Two possessed situs solitus, one with concordant connections and the other with discordant connections; the other had two situs inversus, both of them with concordant ...
