   The Cleveland Clinic detailed how the surgery is done: "A cardiologist (heart specialist) performs a cardiac ablation by inserting a catheter (tube) through a blood vessel to your heart," the site ...

3. Catheter ablation - Wikipedia

   en.wikipedia.org/wiki/Catheter_ablation

   Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.

   For patients with more than 1,000 PVCs per day, the risk of developing left ventricular systolic dysfunction after 5 years follow-up is low. Frequent PVCs may increase the risk of developing cardiomyopathy, which can greatly impair heart function. A PVC burden greater than 10% is the minimal threshold for development of PVC-induced cardiomyopathy.

5. Paroxysmal supraventricular tachycardia - Wikipedia

   Treatment depends on the type of heart rhythm shown on an electrocardiogram test, and the stability of the patient's blood circulation. If a patient has low blood pressure, difficulty breathing, chest pain, shock, or confusion, they are considered unstable and must have an electrocardiogram result checked to determine if the heart is beating ...

   More severe but relatively rare complications include: damage or trauma to a blood vessel, which could require repair; infection from the skin puncture or from the catheter itself; cardiac perforation, causing blood to leak into the sac around the heart and compromising the heart's pumping action, requiring removal using a needle under the ...

   This procedure is performed by cardiac electrophysiologists and has high success rate in the hands of an experienced electrophysiologist. [26] Findings from 1994 indicate success rates of as high as 95% in people treated with radiofrequency catheter ablation for WPW. [ 27 ]
