The bradycardias reported have included sinus bradycardia, sinus arrest, nodal and junctional rhythms, sick sinus syndrome, and all degrees of atrioventricular block.[1,3,7,8,11,18-20] Our patient showed only sinus bradycardia and first-degree atrioventricular block. Some patients were asymptomatic, whereas others experienced symptoms of syncope,[3,7,19] weakness and dizziness,[3,19] fatigue with ambulation,[20] and palpitations.[3] Our patient's fatigue during physical therapy resolved after clonidine was discontinued.
For technical reasons this did not result in complete severance, but did result in first-degree atrioventricular block, which was considered sufficient.
