Right coronary artery procedures are often associated with sinus arrest, atrioventricular block, idioventricular rhythm, and severe hypotension.
Thus, after delay in the atrioventricular mode, atrial contraction is followed by rapid and coordinated contraction of the ventricles.
Atrial tachycardia with atrioventricular block is typically seen with digoxin toxicity.
This acts as the heart's natural pacemaker by conveying electrical impulses to the atrioventricular node, which is located in between the upper and lower chambers.
The decrease in myocardial oxygen consumption was evidenced by a gradual decline in atrioventricular oxygen difference, indicating a decrease in myocardial oxygen uptake relative to supply.
A 29-year-old woman was admitted to the hospital with complete atrioventricular conduction block and severe congestive heart failure.
Prenatal scanning is now so sophisticated that in Britain over half of all cases of hypoplastic left heart and atrioventricular connections involving a single ventricle are now diagnosed before birth.
