One possible cause is convulsive syncope, a seizure-like reaction resulting from global cerebral hypoperfusion that can happen in around 12% of patients presenting with syncope. The history of a patient is very helpful in distinguishing syncope from seizures. Involuntary movements, frequently referred to as myoclonic jerks, may accompany syncope of cardiovascular causes and create a differential diagnostic problem against seizure, with implications regarding therapy.
In this study, investigators assessed motor phenomena in patients either being evaluated for syncope or having presurgical evaluation fo…
