Responses to carotid sinus stimulation before and after propranolol.

The response to carotid sinus stimulation was studied in nine elderly men (mean age 67) with no history of cardiac disease, dizziness, or syncope. The response to manual carotid sinus pressure (during one of two studies) was positive (an RR interval of greater than 3s) in three men. But seven men sh...
