The atrioventricular node (AVN ... pacemaker and providing further insight into basic mechanisms involved in AV conduction. Additionally, procurement of explanted human hearts have provided ...
When SAV+ is activated, the pacemaker will search for the patient's intrinsic AV conduction time and extend the Paced AV (PAV) and Sensed AV (SAV) intervals as needed to promote intrinsic ...
He had a history of atrial fibrillation (AF) that initially occurred 2 years before in the context of streptococcal ...
Type II block may be due to bilateral bundle-branch block occurring below the atrioventricular node. Adrenergic drugs (isoproterenol) and cholinergic blocking drugs (atropine) increase conduction ...
We have demonstrated that overexpression of an inhibitory component of the β-adrenergic signaling pathway suppresses AV nodal conduction, and documented the absence of EP changes after adenovirus ...
This represents a greater disturbance of AV nodal conduction than first-degree AV block, but with exercise there should be a return of 1:1 conduction. The occurrence of IRBBB in an asymptomatic ...
Ischemic heart or peripheral vascular disease. 1 st-degree AV block. Sinus node dysfunction. Conduction disorders (eg, Wolff-Parkinson-White). Monitor HR during therapy. Bronchospastic disease.
