What is the success rate of cardiac ablation?

Cardiac ablation is a low-risk procedure with about a 90 percent success rate, explains the American Heart Association. The risk of complications is low, with most patients resuming normal activities within a few days.

Depending on the type of abnormal heart beat a patient has, radiofrequency ablation or cryoablation may be used to perform cardiac ablation. Though discomfort is minimal during either of the procedures, patients under mild sedation may feel a burning sensation when medicines are injected, a faster or stronger heartbeat, and light-headedness and burning when the electrical energy is used, explains MedlinePlus.

Patients should not to drive or consume alcohol in the 24 hours following the surgery. They should also avoid heavy physical activity for three days, warns the American Heart Association.
