The procedure of rectifying the heart rhythm problems, i.e. arrhythmias is known as cardiac ablation. The tissue in the heart that triggers abnormal heart rhythms are destroyed or scarred through cardiac ablation.
Furthermore, this procedure also helps in preventing the abnormal electrical signals from entering the head. This procedure uses long flexible tubes known as catheters for modifying the tissues in the heart that cause abnormal heart rhythms. A catheter is inserted through an artery or vein in the groin and passed to the heart for delivering energy in the form of extreme cold or heat. Irregular heartbeats are treated by using electrodes to deliver an electric pulse to certain areas of the heart.
This procedure may be performed through open heart surgery, or through minimally invasive catheter procedure. Apart from arrhythmia, this procedure is also useful in treating atrial fibrillation. Cardiac ablation is recommended when the other methods such as medications and cardioversion (resetting the heartbeats) do not work well.
