Key result
Left temporal lobe seizures link to stereotypical bigeminy, illustrating ictal influence on cardiac electrophysiology.
Why the study?
Seizures can influence cardiac autonomic function and cause electrocardiogram abnormalities, but specific ictal cardiac electrophysiology manifestations are not well characterized.
Case Report (n=1)
This case illustrates that ictal brain activity, specifically left temporal lobe seizures, can directly influence cardiac electrophysiology and cause arrhythmias such as bigeminy.
May prompt arrhythmia vigilance during temporal seizures; leaves open insular mechanisms pending confirmatory studies.
Seizures can influence cardiac autonomic function and cause abnormalities in the electrocardiogram (EKG). A case of stereotypical bigeminy during left temporal lobe seizures recorded in the epilepsy monitoring unit is presented. The mechanism is likely due to spread of the ictal discharge to primary visceromotor regions in the left insula (Island of Reil). This case illustrates the potential influence of ictal brain activity on cardiac electrophysiology.

Widdess‐Walsh et al. (2010) conducted a case report in Left temporal lobe seizures (n=1). Left temporal lobe seizures was evaluated on Stereotypical bigeminy on EKG. Left temporal lobe seizures were associated with stereotypical bigeminy, illustrating the potential influence of ictal brain activity on cardiac electrophysiology.
