Outcomes for long QT syndrome patients treated at specialty center are better. Sudden cardiac death, and episodes of fainting and seizures from long QT syndrome are significantly lower than previously thought when patients are diagnosed and treated at a specialty center dedicated to the treatment of genetic heart rhythm diseases, according to research. This is one of the largest studies of long QT syndrome patients -- people who have an inherited heart rhythm condition that can potentially cause fast and chaotic heartbeats -- evaluated and treated at a single center to analyze these outcomes.
