Cardiac Ablation: Treatment for Atrial Fibrillation and Arrhythmias

Cardiac ablation is performed by a Cardiac Electrophysiologist, a cardiologist with specialized training in diagnosing and treating heart rhythm disorders.

Electrophysiologists specialize in:

• Atrial fibrillation treatment
• Catheter ablation procedures
• Cardiac mapping
• Electrophysiology studies
• Pacemakers and implantable cardiac devices
• Ventricular and supraventricular arrhythmias

Cardiac ablation may be recommended for:

The most common sustained heart rhythm disorder, characterized by rapid and irregular heartbeats.

An abnormal electrical circuit in the upper chambers of the heart causing rapid but organized heart rhythms.

Episodes of unusually fast heartbeats originating in the upper chambers of the heart.

A potentially serious arrhythmia arising from the lower chambers of the heart.

A common type of SVT that often responds very well to catheter ablation.

Patients may need to:

• Stop certain medications temporarily.
• Undergo blood tests and cardiac imaging.
• Avoid eating or drinking after midnight.
• Attend a pre-procedure consultation.

The procedure takes place in an electrophysiology laboratory.

Thin catheters are inserted through a blood vessel, usually in the groin, and guided into the heart using advanced imaging technology.

The electrophysiologist identifies the source of the abnormal rhythm and delivers:

• Radiofrequency energy (heat), or
• Cryoablation (extreme cold)

to eliminate the problematic tissue.

Most procedures take between two and four hours, depending on complexity.

Patients are monitored for several hours and may return home the same day or after an overnight stay.

Recovery is generally quick, and most individuals resume normal activities within a few days.

Cardiac ablation offers several important advantages:

• Improved heart rhythm control.
• Reduced frequency of arrhythmia episodes.
• Fewer symptoms such as palpitations and dizziness.
• Reduced need for antiarrhythmic medications.
• Improved exercise tolerance.
• Better overall quality of life.

For many patients with atrial fibrillation, catheter ablation may significantly reduce the risk of recurrent arrhythmias.

Although cardiac ablation is considered safe, potential risks include:

• Bleeding.
• Bruising at the catheter insertion site.
• Blood clots.
• Infection.
• Damage to blood vessels.
• Cardiac perforation.
• Stroke.
• Temporary arrhythmias.
• Reactions to medications or anesthesia.

Your electrophysiologist will discuss individual risks and benefits before the procedure.

Success rates vary depending on the specific arrhythmia being treated.

Many patients experience:

• Long-term symptom relief.
• Improved heart function.
• Fewer emergency room visits.
• Reduced dependence on medication.

In some cases, a repeat ablation procedure may be required to achieve optimal results.

Seek immediate medical attention if you experience:

• Chest pain.
• Shortness of breath.
• Persistent palpitations.
• Severe dizziness.
• Fainting.
• Significant swelling at the catheter site.
• Excessive bleeding.
• Fever or signs of infection.

Heart rhythm disorders can impact both quality of life and long-term cardiovascular health. Early evaluation by a cardiac electrophysiologist can help determine whether cardiac ablation is the right treatment option.

Cardiac ablation is a minimally invasive procedure that destroys small areas of heart tissue responsible for abnormal electrical signals.

Yes. Cardiac ablation is one of the most effective treatments for atrial fibrillation in selected patients.

Most procedures take between two and four hours.

Patients typically receive sedation or anesthesia and experience minimal discomfort.

Most patients return to normal activities within several days.

Success rates vary depending on the arrhythmia but are generally high for many common rhythm disorders.

Yes. Some patients may experience recurrence and occasionally require additional treatment.

A Cardiac Electrophysiologist performs the procedure.

For many patients, catheter ablation can provide more effective long-term rhythm control than medications alone.

You should seek evaluation if you experience palpitations, irregular heartbeats, dizziness, fainting, or a diagnosis of atrial fibrillation or another arrhythmia.
