Central control of cardiac activity as assessed by intra-cerebral recordings and stimulations
2023, Neurophysiologie CliniqueIctal asystole as a manifestation of pure insular epilepsy
2021, SeizureCitation Excerpt :Taken all together, extra-insular regions were unlikely to be involved in the generation of ictal asystole in our patient. A previous report using SEEG has shown that a left amygdalo-hippocampal seizure with ipsilateral insular propagation led to asystole [3]. Although left-sided lateralization had been suggested in the parasympathetic cardiac regulation, bilateral representation has been confirmed by a recent study of direct insular stimulation using SEEG [4].
Ictal asystole during long-term video-EEG; semiology, localization, and intervention
2021, Epilepsy and Behavior ReportsCitation Excerpt :Stimulation of the left hippocampus resulted in IA lasting 11 seconds after the EEG onset. This was the first study to show that stimulation-induced seizures in humans could cause ictal asystole [15]. Stimulation of the posterior long gyrus of the insula on the left also caused bradycardia.
Keeping pace: A 38-second ictal asystole revealed during simultaneous electroencephalogram and electrocardiogram monitoring
2018, HeartRhythm Case ReportsCitation Excerpt :Even in high-volume neurology centers, ictal-induced bradycardia and asystole are documented in <0.5% of patients undergoing video-electroencephalogram (vEEG) recording.2,3 The mechanism of ictal-induced bradycardia and asystole has yet to be fully elucidated, though it is hypothesized to be related to cortical control of the autonomic system by either sympathetic inhibition or vagal activation, leading to sinus node arrest.4–6 Seizures can lead to cardiac bradycardia or asystole, while cardiac bradycardia can lead to convulsions.
Planning and management of SEEG
2018, Neurophysiologie CliniqueCitation Excerpt :Better knowledge of specific subjective manifestations makes it easier to recognize these. Technical progress has progressively allowed sampling of the insula under good safety conditions and through identifying the anatomo-functional characteristics [47,87–95]. SEEG is particularly effective in demonstrating an insular origin of seizures (Fig. 3).
