In order for the heart to beat, it receives electrical stimulation or signals that starts in the atria or upper chambers of the heart and then travel down to the ventricles or lower chambers of the heart. This electrical stimulation is referred to as the conduction system of the heart.
The intrinsic conduction system sets the basic rhythm of the beating heart.

Atrial fibrillation is defined as chaotic or abnormal electrical signals or pathways in the atria resulting in an irregular heartbeat. The irregular heartbeat does not allow the atria to contract or squeeze normally, rather the atria quiver decreasing the amount of blood ejected from the heart with each heartbeat.
Catheter (radiofrequency) ablation is a non-surgical treatment option for atrial fibrillation that locates and destroys abnormal electrical pathways in the heart that cause atrial fibrillation. This procedure involves inserting several catheters (tubes) into the heart and locating the abnormal pathway. Once found, the pathway is destroyed with radiofrequency energy. This burning, or ablating, prevents the pathway from conducting electricity. If the abnormal pathway cannot conduct electricity, it cannot initiate atrial fibrillation.
Patients undergoing catheter (radiofrequency) ablation are diagnosed and treated in the Electrophysiology Laboratory by specially trained cardiologists called electrophysiologists, physicians who focus on the electrical or rhythm system of the heart.
