Randomized Controlled Trial Multicenter Study Clinical Trial
SAFE PACE 2: Syncope and Falls in the Elderly--Pacing and Carotid Sinus Evaluation: a randomized controlled trial of cardiac pacing in older patients with falls and carotid sinus hypersensitivity.
SAFE PACE is a multicentre randomized controlled trial to assess the efficacy of dual-chamber pacing in older patients with carotid sinus hypersensitivity and recurrent unexplained falls. Patients are eligible if they have had two or more unexplained falls (+/- up to one syncope) and if they have a cardio-inhibitory response (>3 s asystole) to carotid sinus massage. ⋯ The primary outcome measure is the number of patients who fall in the 24-month follow-up period. Recruitment began in October 1998 and continues for 12 months; the follow-up is for 24 months.

Randomized Controlled Trial Multicenter Study Clinical Trial
Prospective, randomized study of atrioventricular ablation and mode-switching, dual chamber pacemaker implantation versus medical therapy in drug-resistant paroxysmal atrial fibrillation. The PAF study. Paroxysmal Atrial Fibrillation.
We performed a prospective randomized 6-month evaluation of the clinical effects of atrioventricular junctional ablation together with placement of a DDDR mode-switching pacemaker vs pharmacological treatment in 43 patients with intolerable paroxysmal atrial fibrillation not controlled with antiarrhythmic drugs. Ablation and pacemaker treatment were highly effective and superior to drug therapy in controlling symptoms and improving quality of life. However, discontinuation of drug therapy exposed patients to further recurrences of paroxysmal atrial fibrillation and the risk of developing permanent atrial fibrillation.
