Ablation is also known as cardiac ablation. Cardiac ablation is a test that can correct abnormal heart rhythm problems (cardiac arrhythmia). It scars or destroys the tissue in your heart that initiates an abnormal heart rhythm. In some of the cases, the cardiac ablation stops the abnormal electrical signals to reach your heart and, thus it stops cardiac arrhythmias. The doctor uses a catheter that is inserted through a vein or artery in your groin region and directed towards your heart, then it delivers energy in the form of heat (radiofrequency) or extreme cold (cryoablation) to modify the tissues that cause abnormal heartbeat rhythm. Cardiac ablation is a treatment for the people who have tried medications for heart arrhythmia or had side effects with the medications, or either has a certain types of arrhythmia or high-risk complications such as sudden heart attack.
The cardiac ablations are of 4 types atrial flutter ablation, pulmonary vein isolation, SVT ablation, and ventricular tachycardia ablation.
