title: Narrow-QRS and Wide-QRS Tachycardias.
abstract: In a woman with rheumatic heart disease, atrial flutter with a rapid ventricular response, and congestive heart failure, treatment with digoxin slows conduction in the atrioventricular node and thus allows atrioventricular conduction to occur by way of a previously unrecognized accessory pathway.
