title: Effect of clonidine on atrioventricular conduction.
abstract: Clonidine hydrochloride may be a factor in producing a high-grade atrioventricular block. Therefore, careful follow-up with repeated ECG monitoring seems to be indicated when clonidine is given to a patient with suspected cardiac conduction disease, especially if the patient is concurrently receiving digitalis therapy.
