Atrial Pressure Electrophysiology Pilot Study

This study examined data elements of hemodynamic, electrophysiologic and electrolyte trends
comparing 2 different types of catheters used during a procedure to treat medication
resistant atrial fibrillation-radiofrequency catheter ablation. A high flow catheter delivers
a high volume of saline during the procedure. The low flow catheter delivers a low volume of
saline during the procedure. The patient will be consented and randomized to one of the 2
groups using a computer generated randomization chart. Those that are put in the low flow
catheter group will be considered the experimental group. All data will be collected before
and after the procedure and each patient will act as their own control within each group.
