“A 29-year-old woman was admitted to the hospital with complete atrioventricular conduction block and severe congestive heart failure.”

“Right coronary artery procedures are often associated with sinus arrest, atrioventricular block, idioventricular rhythm, and severe hypotension.”

“In some patients the atrioventricular node allows retrograde conduction of ventricular impulses to the atria.”

“Digoxin is incapable of converting atrial fibrillation or atrial flutter to a normal sinus rhythm.”

“The resultant irregular rhythm may be difficult to differentiate from atrial fibrillation.”

“For Protocol 4, animals were instrumented before delivery to measure pulmonary artery pressure and left atrial pressure.”
