Abstract:
Although calcium channel blockers have been reported to aggravate Brugada-type electrocardiogram (ECG) abnormalities, there have been few reports in clinical settings. We present a case of Brugada syndrome coexisting with vasospastic angina, in whom Brugada-type ST-segment elevation was aggravated and ventricular fibrillation attacks occurred by calcium channel blocker treatment. When prescribing calcium channel blockers to patients with Brugada syndrome, it is important to pay careful attention to changes in their ECG pattern.

Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
