“…The patient suffered symptoms such as jamais vu, which were suggestive of partial seizures. The attack was usually developed while eating, but it was different from situational syncope such as swallowing syncope that is caused by a reflex of the involuntary nervous system called the vasovagal reaction 10). To rule out situational syncope, we performed EEG analysis, which showed rhythmic theta activity and sharp waves in the left temporal area and generalized rhythmic theta activity.…”

Ictal asystole is potentially lethal, and known to originate from the involvement of limbic autonomic regions. Appropriate treatment must include an antiepileptic drug and the implantation of a pacemaker. We report the case of a 54-year-old male with recurrent syncope secondary to ictal asystole triggered by temporal lobe epilepsy. This was confirmed by combined Holter and video-electroencephalogram monitoring.

Background and Objectives Neurocardiogenic syncope is believed to be caused by a transient imbalance of autonomic nervous system. Actually, there were significant differences in heart rate variability HRV indices during head-up tilt test between patients with neurocardiogenic syncope and normal controls. But there was no definite evidence for it during daily activity. So, we tried to evaluate HRV during daily activity with 24-hour ambu-latory electrocardiography monitoring. Materials and Methods 27 patients with neurocardiogenic syncope or presyncope mean age 45 3 and 25 normal volunteers mean age 47 2 comparable for age and sex underwent 24-hour ambulatory electrocardiography. Head-up tilt test was used to diagnose neurocardiogenic syncope or presyncope in patients group. HRV was analysed over the whole 24 hours, using time and frequency domain parameters. Student's t-test was applied. Results There were no significant differences in HRV measures between two groups, over 24-hour period and day-time and night-time period. But the hourly HRV measures showed a transient decrease of LF, LFnorm and LF HF ratio in patients group compared to normal control group. Conclusions These results indicate that patients with neurocardiogenic syncope or presyncope suffer from temporarily decreased sympathetic tone with normal parasympathetic tone. So, transient additive change of autono-mic nervous tone may cause syncope or presyncope in these patients. Korean Circulation J 2000 ; 30 6 : 716-723
