May warrant genetic evaluation in unexplained infant VT with conduction disease; leaves open screening recommendations pending larger confirmatory studies.
Do infants with rapid ventricular tachycardia and conduction abnormalities without structural or metabolic disease have mutations in cardiac depolarizing channels?
Infants presenting with rapid ventricular tachycardia and conduction abnormalities without structural heart disease should undergo genetic testing for depolarizing channel mutations such as those causing Brugada syndrome.
Kanter et al. (2011) studied this question.
