Long QT syndrome, KCNQ1-related(LQTS)
Also known as: Long-QT-Syndrom Typ 1 · LQT1 · KCNQ1-associated Long QT Syndrome · Congenital Long QT Syndrome · Canine Long QT Syndrome
Overview
What it is
Long QT syndrome (KCNQ1-related) is an inherited heart condition that affects the cardiac electrical system. It delays the time it takes for the heart muscle to recharge its electrical system after each beat. This delay can disrupt the normal heart rhythm, potentially leading to dangerous, irregular heartbeats.
How it presents
Symptoms typically appear in young to middle-aged dogs and are often triggered by physical exertion or sudden excitement. Owners may notice weakness, sudden fainting spells, or in severe cases, sudden collapse.
Treatment
This is a lifelong condition that cannot be cured but can be managed with daily medications and regular heart monitoring. Ongoing veterinary care and treatment typically cost between 1,500 and 6,000 EUR.
How it's tested
Long-QT-Syndrom (KCNQ1) DNA-Test(LQTS)
Primary testDNA testDieser DNA-Test identifiziert die ursächliche Mutation im KCNQ1-Gen, die für die verzögerte elektrische Regeneration des Herzmuskels verantwortlich ist.
