Restoring a regular heartbeat

Cardiac catheter ablation is used to control irregular heart rhythms (arrhythmia). During the ablation, a catheter is threaded up through the groin into the heart. It releases radiofrequency energy to scar the heart tissue that’s causing the arrhythmia. Depending on the type of arrhythmia you have, ablation offers success rates as high as 95 percent.

Treating a variety of heart rhythm disorders

Atrial fibrillation
This is the most common type of arrhythmia. It occurs when the upper chambers of the heart beat very rapidly (300–600 beats per minute) and irregularly. When the heart beats inefficiently, not enough blood is pumped to the rest of the body. This can cause shortness of breath, fatigue and an increased risk of stroke.

Atrial flutter
This form of arrhythmia occurs suddenly when the heart beats rapidly at about 200–300 beats per minute, with a “short circuit” occurring in the right upper chamber of the heart. Ablation cures atrial flutter in 90–95 percent of patients.

Ventricular tachycardia
Tachycardia is a rapid but regular heartbeat of over 100 beats per minute that originates in the lower heart chambers (ventricles). In most cases, it’s caused by heart disease such as a previous heart attack; it can also be an inherited heart rhythm disorder. Ventricular tachycardia can be deadly depending on your overall heart function. Treatments to control the heart rate and prevent future episodes range from medication to ablation and/or defibrillation implant.

Supraventricular tachycardia (SVT)
Like ventricular tachycardia, supraventricular tachycardia is a regular heartbeat faster than 100 beats per minute that originates in or above the upper heart chambers (atrioventricular node). In most cases, an extra electrical connection in the heart causes SVT. Common causes also include Wolff-Parkinson-White Syndrome. Treatment with ablation is a highly effective, low-risk therapy with a 90–95 percent cure rate.
