Cardiac pacing is the therapy of choice in syncope patients with documented asystole (>3 s) in response to carotid sinus massage, or on ambulatory ECG recording (Kenny et al., 2001). The vasodepressor type is likely to benefit from general orthostatic tolerance enhancing measures such as salt and volume loading, and there is some evidence that fludrocortisone may be effective (Hussain et al., 1996). However up to date there are no large scale clinical trials confirming this. | Cardiac pacing is the therapy of choice in syncope patients with documented asystole (>3 s) in response to carotid sinus massage, or on ambulatory ECG recording (Kenny et al., 2001).
