Syncope due to ictal asystole..Met Synd Thrombolysis in MCA Ischemic Stroke
In each case, simultaneous EEG and electrocardiogram recordings identified the cause of the falls. The cases, supplemented by video clips on the Neurology website, provide convincing demonstrations of falls associated with seizure-induced asystole. Comment: As is noted in an editorial, sudden falls are potentially dangerous in themselves. Even though a connection has not been established between ictal bradycardia or asystole and the phenomenon of sudden unexpected death in epilepsy, patients with seizure-induced cardiac asystole probably should be treated not only with the best available antiepileptic therapy, but also with cardiac pacing. The report also highlights the complex interactions between cerebral and cardiovascular dysfunctions that contribute to episodic unconsciousness. Clinicians must keep in mind that the spectrum of episodic unconsciousness includes not only ictal asystole but also the more common phenomenon of convulsive syncope (convulsive movements due to cerebral hypoperfusion without an epileptic discharge) and very rare cases of hypoperfusion-induced acute symptomatic seizures. — Edward B.

Although most seizures are associated with sinus tachycardia, a minority are associated with bradycardia and even asystole (which is usually defined as a sinus pause lasting at least 3 seconds).
