What is an Ablation of Cardiac Arrhythmias?

Ablation of cardiac arrhythmias is a medical procedure used to treat abnormal heart rhythms (arrhythmias). It involves destroying small areas of heart tissue that are causing irregular electrical signals.

What happens during an Ablation of Cardiac Arrhythmias?

During ablation, the catheter is inserted into a vein, usually in the groin, and guided to the heart. The doctor uses heat (radiofrequency) or cold (cryoablation) energy to destroy the problematic heart tissue. The procedure typically lasts 2 to 4 hours.

Why would I need an Ablation of Cardiac Arrhythmias?

You might need ablation if:

• You have arrhythmias that are not controlled by medication

• Your arrhythmias cause significant symptoms such as palpitations, dizziness, or fainting

• You have a high risk of complications from arrhythmias, such as stroke or heart failure

 

Who needs an Ablation of Cardiac Arrhythmias?

Ablation may be necessary for:

• Patients with atrial fibrillation, atrial flutter, or other types of arrhythmias

• Individuals who do not respond to or cannot tolerate anti-arrhythmic medications

• Those at high risk of arrhythmia-related complications

 

What are the risks of an Ablation of Cardiac Arrhythmias?

Ablation involves some risks, including:

• Bleeding or infection at the catheter insertion site

• Damage to blood vessels or the heart

• Arrhythmias or heart block requiring a pacemaker

• Rarely, stroke or other serious complications

 

It's important to note that these risks are rare and the benefits of the test typically outweigh the risks. Additionally, the test is performed under the supervision of trained medical professionals who are equipped to handle any complications that may arise. Your doctor will review your medical history and assess your overall health to determine whether the benefits of the test outweigh the risks for you. If you have concerns about the risks of a stress echocardiogram, discuss them with your doctor before the test.


How do I prepare for an Ablation of Cardiac Arrhythmias?

To prepare for ablation:

 

• Follow your doctor’s instructions, which may include fasting for several hours before the procedure.

• Inform your provider of any allergies and medications you are taking.

• Arrange for someone to drive you home after the procedure, as you may be sedated.

• Wear comfortable clothing and remove any jewelry or metal objects.
