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 ...

Iatrogenic Atrioventricular Block

Cardiac Electrophysiology Clinics, 2021
Iatrogenic atrioventricular (AV) block can occur in the context of cardiac surgery, percutaneous transcatheter, or electrophysiologic procedures. In cardiac surgery, patients undergoing aortic and/or mitral valve surgery are at the highest risk for developing perioperative AV block requiring permanent pacemaker implantation.

Atrioventricular block after reciprocating atrioventricular junctional tachycardia

The American Journal of Cardiology, 1975
Short 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 ...

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 ...

Crossed atrioventricular connections

American Heart Journal, 1980
Four 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 ...

Atrioventricular nodal parasystole∗

The American Journal of Cardiology, 1964
Abstract 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 ...

Complex Atrioventricular Canal

Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2007
Complex forms of atrioventricular (AV) canal (C) such as; AVC with left ventricular outflow tract obstruction, tetralogy of Fallot with complete AVC, double orifice left AV valve, unbalanced complete AVC, and single ventricle patients with common AVC valve require careful preoperative planning and special techniques.
