What part of heart does "long qt syndrome" affect?
3 doctors weighed in across 2 answers
Electrical system: Long qt is a genetic syndrome that causes abnormal behavior of the ion channels in the cardiac muscle, which alters the electrical behavior of the heart. This can make people prone to dangerous arrhythmias, which may progress to cardiac arrest.
