Novel cardiac manifestation of USH2A and GJB2 genes: A case report

Abstract

Electrical storm can be caused by structural heart diseases and/or functional electrical abnormalities. We report a young boy without cardiac risk factors, having a positive family history of sudden cardiac death who presented with electrical storm. Stepwise diagnostic approach was not fruitful to determine previously known causes as the origin of the electrical storm. A new genotype related to the current electrical storm has been found, and intracardiac pacing ceased it.
