Key result
In a systematic review of patients with isolated ictal asystole and syncope, all cases were diagnosed with temporal lobe epilepsy and experienced a mean cardiac arrest duration of 15.1 seconds.
Why the study?
Ictal syncope is a rare phenomenon occurring in 0.002-0.4% of seizures, and in the absence of other symptoms, seizures presenting with syncope can be challenging to diagnose.
Does anti-seizure medication and cardiac pacemaker placement improve symptoms in patients with ictal asystole and isolated syncope?
Case Report (n=8)
Does anti-seizure medication and cardiac pacemaker placement improve symptoms in patients with ictal asystole and isolated syncope?
Seizures should be considered in the differential diagnosis of patients with syncope of uncertain etiology, as ictal asystole can be effectively treated with anti-seizure medications and cardiac pacing.
Ictal asystole signals temporal lobe epilepsy in syncope; supports epilepsy evaluation and ASM or pacing consideration.
Ictal syncope is a rare phenomenon that occurs in association with 0.002-0.4% of seizures. In the absence of other symptoms, seizures presenting with syncope may be challenging to diagnose. We report a case of a previously healthy male who developed recurrent episodes of syncope with postictal confusion and was later diagnosed with temporal seizures. The patient was successfully treated with anti-seizure drugs and placement of a cardiac pacemaker. In a systematic review of literature, we summarize the clinical characteristics of patients with ictal asystole and isolated syncope. Seizures should be considered in patients with syncope of uncertain etiology.

Li et al. (2018) conducted a case report in Ictal asystole with isolated syncope (n=8). Anti-seizure medications and cardiac pacemaker was evaluated on Clinical characteristics and duration of cardiac arrest. In a systematic review of patients with isolated ictal asystole and syncope, all cases were diagnosed with temporal lobe epilepsy and experienced a mean cardiac arrest duration of 15.1 seconds.
