Atrioventricular Dissociation

The American Journal of Emergency Medicine, 2001
Atrioventricular (AV) dissociation is an electrocardiographic syndrome; a descriptive term for a variety of conditions of abnormal cardiac conduction which all feature independent function of the atria and ventricles. AV dissociation can be subclassified as AV dissociation by default (an independent ventricular pacemaker responds to slowing of the ...

ANATOMY OF THE ATRIOVENTRICULAR NODE AND ATRIOVENTRICULAR CONDUCTION SYSTEM

International Journal of Bifurcation and Chaos, 2003
The 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 ...

Atrioventricular block and problems with atrioventricular conduction

Clinics in Geriatric Medicine, 2002
This 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, 2011
A 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, 1997
Atrioventricular 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

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 and Atrioventricular Dissociation

2004
Atrioventricular (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
