Atrial fibrillation is the condition where the heart beats irregularly with weak or untimely heartbeats. One of the treatments for this disease is using heat or cold energy to neutralize the irregular signals and achieve a regular heartbeat rhythm. The treatment is performed when medication treatments fail. It may also be done during cardiac surgery with the help of thin flexible tubes called catheters. The catheters are used to make small scars, burns or freezes on the heart muscle using radiofrequency energy. This stops the heart from conducting abnormal electric signals. The longevity of the ablation procedure depends on the time you were having the fibrillations.
