Supraventricular Tachycardia (SVT) ablation in Dubai at Emirates Hospital Jumeirah. SVT ablation is a medical procedure used to treat abnormal rapid heart rhythms originating from the upper chambers of the heart (atria). These abnormal rhythms can cause episodes of palpitations, dizziness, chest discomfort, and in severe cases, can lead to fainting or heart failure. At Emirates Hospitals our Electrophysiology Clinic is performed by our Expert US Board Certified Electrophysiologist.

The SVT Procedure

During the SVT ablation procedure, the patient is usually under conscious sedation or general anesthesia to ensure comfort and safety. A thin, flexible tube called a catheter is inserted through a blood vessel, typically in the groin or arm, and guided to the heart using fluoroscopy (X-ray) and electrocardiogram (ECG) guidance.

Once the catheter reaches the heart, the electrophysiologist, a specialized cardiologist, delivers electrical signals through the catheter to induce the abnormal rhythm. This helps the medical team pinpoint the exact location and mechanism of the arrhythmia.

Next, the main goal of the ablation is to eliminate or modify the specific area or pathway causing the abnormal rhythm. This is achieved through the use of either radiofrequency energy or cryoablation (extreme cold) delivered through the catheter. Radiofrequency ablation generates heat to create tiny scars that block the abnormal electrical signals, while cryoablation freezes the targeted tissue to achieve the same result.

During the procedure, the electrophysiologist carefully monitors the heart’s electrical activity and may perform additional ablations if necessary. Once the abnormal pathway or focus has been successfully modified or blocked, the catheter is removed, and pressure is applied to the puncture site to prevent bleeding.
