Cardiac Radio Frequency Ablation

 Cardiac Radio Frequency AblationA test that evaluates the electrical activity within the heart. The test is used to help the doctor determine the cause of the abnormal heart rhythm and find the best treatment. During the test, the doctor may safely reproduce the abnormal heart rhythm and give the patient medications to determine which medication works best to control the abnormal heart rhythm.Radiofrequency ablation (RFA) is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from high frequency alternating current (in the range of 350–500 kHz).[1] RFA is generally conducted in the outpatient setting, using either local anesthetics or conscious sedation anesthesia.Two important advantages of RF current (over previously used low frequency AC or pulses of DC) are that it does not directly stimulate nerves or heart muscle and therefore can often be used without the need for general anesthetic, and that it is very specific for treating the desired tissue without significant collateral damage.

Documented benefits have led to RFA becoming widely used during the last 15 years.[2][3] RFA procedures are performed under image guidance (such as X-ray screening, CT scan or ultrasound) by an interventional pain specialist (such as an anesthesiologist), interventional radiologist, otolaryngologists, a gastrointestinal or surgical endoscopist, or a cardiac electrophysiologist, a subspecialty of cardiologists.
