Key result
Inherited primary arrhythmia syndromes are frequently masked in patients with sudden cardiac death and coronary vasospasm, necessitating careful evaluation for underlying channelopathies even when spasm is proven.
Supports channelopathy evaluation in SCD despite proven vasospasm; leaves open prospective validation before practice change.
See the article "Masked inherited primary arrhythmia syndromes in sudden cardiac death patients accompanied by coronary vasospasm" in volume 32 on page 836.

Kim et al. (2017) conducted an editorial in Sudden cardiac death and coronary vasospasm. Inherited primary arrhythmia syndrome (IPAS) was evaluated. Inherited primary arrhythmia syndromes are frequently masked in patients with sudden cardiac death and coronary vasospasm, necessitating careful evaluation for underlying channelopathies even when spasm is proven.
