Key result
In a 79-year-old man with hyperthyroidism and early repolarization, treatment with an implantable cardioverter-defibrillator and calcium-channel antagonists prevented recurrence of ventricular fibrillation and anginal attacks over a one-year follow-up.
Case Report (n=1)
ICD insertion combined with calcium channel antagonists successfully prevented recurrence of ventricular fibrillation and anginal attacks in a patient with vasospastic angina, early repolarization, and hyperthyroidism.

May support ICD plus calcium antagonists for VF prevention in VSA; leaves open hyperthyroidism or J-wave effects.
Vasospastic angina (VSA) has been recognized as a cause of ventricular fibrillation (VF) degenerating into sudden cardiac death. We experienced a case of VSA with hyperthyroidism in which VF was provoked with an augmented J-wave amplitude in the inferior leads. The patient underwent insertion of an implantable cardioverter-defibrillator for the secondary prevention of VF in addition to taking Ca-channel antagonists. He has shown no recurrence of fatal arrhythmia or anginal attack for a follow-up period of one year.

Iiya et al. (2018) conducted a case report in Vasospastic angina with hyperthyroidism and early repolarization (n=1). Implantable cardioverter-defibrillator and Ca-channel antagonists was evaluated on Recurrence of fatal arrhythmia or anginal attack. In a 79-year-old man with hyperthyroidism and early repolarization, treatment with an implantable cardioverter-defibrillator and calcium-channel antagonists prevented recurrence of ventricular fibrillation and anginal attacks over a one-year follow-up.
