Treatments

Treatment of LQTS may range from lifestyle changes, to medications, to medical devices to surgery.

Lifestyle changes

If your symptoms are mild or infrequent, your doctor may urge you to adopt certain lifestyle changes to reduce symptoms. These may be on their own or in addition to medications or other treatments. The lifestyle changes could include avoiding strenuous exercise and managing stress, for example.

Medications


Beta Blockers

Most commonly, beta blockers are prescribed for LQTS. These drugs slow the heart rate.

Potassium Pills

Potassium pills may also be prescribed as they may help the heart's ability to recharge.

Artificial Pacemaker


Implanted Under Your Collarbone

This device may be either temporarily or permanently implanted under the skin in the chest wall. It is the most common treatment for arrhythmias that causes symptoms such as fainting.

Pacemaker Insertion

Wallet-Sized, Battery-Powered Device

The wallet-sized, battery-powered device has wires and electrodes attached. The electrodes are threaded through your veins and into your heart, while the pacemaker itself is implanted under your collarbone.

Provides Electrical Impulses Through Electrodes

The pacemaker provides electrical impulses through the electrodes to regulate your heartbeat. In some cases, a dual-chamber pacemaker may be implanted. It has electrodes in both the atria and the ventricles. A traditional pacemaker only has electrodes in the ventricles.

When your heart rate slows, the pacemaker takes over, providing the impulses required to maintain a normal rhythm. Blood thinners may be prescribed along with the pacemaker, at least initially.

Surgery

People at high risk of death from LQTS may be treated with surgery to cut the nerves that prompt the heart to beat faster in response to physical or emotional stress. This helps to keep your heart beating at a steady pace and decreases the chances of developing dangerous heart rhythms in response to stress or exercise.
