The 20 Best Long QT Syndrome Doctors Near Me in Phoenix,, AZ

Long QT syndrome is a heart disorder characterized by rapid, irregular heartbeats caused by a signaling abnormality in the heart’s electrical system. The QT interval refers to the time it takes for the heart’s electrical system to make the ventricles of the heart contract and then recover. In long QT syndrome, there is a delay in the time it takes for the electrical system to recover between each heartbeat. This delay can cause rapid, irregular, and life-threatening ventricular contractions, also known as torsade de pointes.
