Do complete electrophysiological studies identify actionable abnormalities in patients with unexplained syncope?
Electrophysiologic studies have a high diagnostic yield (74%) in patients with unexplained syncope, frequently identifying abnormalities that guide targeted therapy such as pacemakers or antiarrhythmic drugs.
Denes et al. (1985) conducted an observational in Unexplained syncope (n=50). Electrophysiologic studies was evaluated on Abnormal electrophysiologic study. Complete electrophysiological studies revealed abnormalities in 74% of consecutive patients with unexplained syncope.
