Paroxysmal atrioventricular block
Heart Rhythm, 2009Paroxysmal atrioventricular block (AVB) is a poorly defined clinical entity characterized by abrupt and unexpected change from 1:1 atrioventricular conduction to complete heart block, leading to syncope and potential sudden cardiac death. Although a dangerous condition because of unreliable escape mechanism, proper diagnosis of paroxysmal AVB is often ...

Heart Rhythm, 2022
Specific pacing methods to unmask the existence of the dual atrioventricular (AV) nodal pathway in patients with dual AV nodal non-reentrant tachycardia remain to be established.This study aimed to determine the electrophysiological characteristics of dual AV nodal non-reentrant tachycardia by its responses to specific pacing methods.Five patients ...

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

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 ...

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!

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

Atrioventricular Node Ablation
Heart Failure Clinics, 2015Cardiac 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 revisited
Comprehensive Therapy, 2002AV blocks, their definitions and significance, are discussed. Type II, second-degree AV block is infranodal, whereas 2/3 of Type I with BBB are infranodal, 2:1 AV block is neither Type I nor II block. Infranodal blocks require pacing regardless of symptoms.
