Abstract
Long QT syndrome (LQTS) predisposes to syncope and sudden cardiac death. Type 5 LQTS, linked to KCNE1 variants, is rare. A teenage female presented with recurrent syncope. ECG showed QTc 485 ms. Genetic testing identified KCNE1 and RYR2 variants. Beta-blockers and ICD prevented events. The case highlights diagnostic and genotype-phenotype challenges.
