Abstract
Syncope is common in almost all the age groups and affects around 40% of people during their lifetime. There are many etiologies among which carotid hypersensitivity is a rare and important cause. Carotid sinus activity causes cardio inhibitory type of bradycardia or hypotension. We describe a case of 70 year old male who presented to us with recurrent attacks of syncope and was diagnosed as carotid sinus syncope with sick sinus syndrome.
