Does cardiac pacing using the Thera DR rate-drop response algorithm reduce recurrent symptoms in patients with carotid sinus syndrome or vasovagal syncope?
The Thera DR rate-drop response pacing algorithm appears beneficial in reducing the frequency and severity of symptoms in highly symptomatic patients with carotid sinus syndrome or vasovagal syncope.
Benditt et al. (1997) studied Carotid sinus syndrome or vasovagal syncope (n=43). Thera DR rate-drop response pacing algorithm was evaluated on Absence or diminished frequency of symptoms, or less severe symptoms. Cardiac pacing using the Thera DR rate-drop response algorithm resulted in absent or diminished symptoms in 80% of highly symptomatic patients with carotid sinus syndrome or vasovagal syncope.
