Treating long QT syndrome

Most people with inherited long QT syndrome will need treatment with medicines. Beta-blockers , such aspropranololornadolol, may be prescribed to help control irregular heartbeats and slow down your heart rate.

If your symptoms are frequent or severe, and you have a high risk of having a life-threatening arrhythmia, you may need to have a pacemaker or implantable cardioverter defibrillator (ICD) fitted.

Like pacemakers, ICDs are small battery-powered devices. If the ICD senses that the heart is beating at a potentially dangerous abnormal rate, it will deliver an electric shock that returns the heart rhythm to normal.

In some cases of long QT syndrome, surgery may be needed to control the flow of chemicals into the heart.

If you have long QT syndrome caused by taking medication, your medication will be reviewed. It may be possible to prescribe alternative medication that doesn't adversely affect your QT interval.
