QT prolongation syndrome is a heart signaling disorder that can cause fast, chaotic heartbeats (arrhythmias). It can be present from birth or develop later in life due to certain medical conditions, specific drugs, or mineral imbalances.
Your doctor may ask these questions to check for this disease:
Treatment involves lifestyle changes and medications to prevent dangerous heartbeats. In some cases, surgery may be necessary to implant a device that controls the heart's rhythm.
