Two syndromes, hypersensitive carotid sinus reflex (HCSR) and "sick sinus syndrome" (SSS) were studied in 28 patients, 6 of whom served as controls. Carotid sinus pressure was performed during sinus rhythm (CSP 1) and atrial stimulation just above the sinus rate (CSP 2). Overdrive suppression was also tested. Vagal stimulation provoked different effects in… CONTINUE READING
