Recording for Potential AF Drivers and Patient Specific Atrial Anatomy & Atrial Electrogram Maps (CONFIRM)
The 64 pole basket catheter used for the mapping procedure will be defined "atypical" sites which sustain atrial fibrillation. The ablation through the driver will lead to more rapid ablation of the atrial fibrillation.

Procedure: 64 pole basket catheter
Atrial fibrillation (AF) is a common abnormal and rapid heart rhythm characterized by erratic electrical activity of the upper chambers of the heart. This cardiac arrhythmia may lead to stroke, heart failure, low blood pressure, chest pain, and increased mortality rate. Treatment may include medication to stop the rhythm abnormality, blood thinners, and/or ablation. Ablation involves application of heat or freezing to the area sustaining the rhythm abnormality. This requires tubes (catheters)to be placed in the heart. Human atrial fibrillation may be sustained by localized drivers (rapid and/or organized sites of atrial electrical activation). By mapping/recording the patient's specific atrial anatomy and atrial electrical activity with the 64-pole basket catheter, we may add to the knowledge base of these driver locations. We may also add to the knowledge about where best to ablate to terminate the arrhythmia. Typical anatomic
