Title: [Hypersensitive carotid sinus reflex in older patients. Incidence and significance for the diagnosis of sick sinus node].
Abstract: Carotid sinus massage was performed in 100 consecutive patients over the age of 50 years: 63 showed a normal reaction and sinus bradycardia occurred in 12, whereas sinus arrest was registered in 22 and total AV block in 3. With atrial pacing only 2 patients with sick sinus syndrome could be detected. Intravenous administration of atropine did not help to identify them. We conclude that in 1/4 to 1/3 of these elderly people the sinus node reacts in a hypersensitive manner to carotid sinus massage, but this does not imply the diagnosis of sick sinus syndrome.
