Ocular timolol as the causative agent for symptomatic bradycardia in an 89-year-old female.

In this paper we present the case of an 89-year-old female presenting with symptomatic bradycardia for whom the cause was found to be ophthalmic timolol which she had been taking for four years. Prompt recognition of potential causes of bradycardia is essential for correct selection of treatment and disposition.
