During 22 episodes of induced ventricular arrhythmias in 14 patients, conspicuous motor activity accompanied unconsciousness in 10 episodes, complicating the clinical distinction from seizures.

No
Syncope from malignant ventricular arrhythmias can present with motor activity mimicking seizures, but EEG confirms the absence of electrographic seizure activity.

Arrhythmic syncope may mimic seizures via motor activity; case reports leave open arrhythmia evaluation in unexplained events.
Michael J. Aminoff (1988) conducted an observational in Malignant ventricular cardiac arrhythmias (n=14). Deliberate induction of cardiac dysrhythmia was evaluated on Electrocerebral and clinical accompaniments of syncope. During 22 episodes of induced ventricular arrhythmias in 14 patients, conspicuous motor activity accompanied unconsciousness in 10 episodes, complicating the clinical distinction from seizures.
