Arm Intervention/treatment
Experimental: Multistage low-energy stimulation
Multistage low-energy electrical pulses as described in Janardhan AH et al. JACC 2014 Jan7-14:63(1):40-8 will be delivered to a patient in atrial fibrillation. The responses to these stimuli will be recorded.
Device: Multistage low-energy stimulation
The parameters of the Multistage waveform will be altered and the response of the atria will be recorded.

Primary Outcome Measures :
  1. Safety and Efficacy of Multistage low-energy pulses to organize, suppress, or terminate atrial fibrillation as determined by changes in atrial fibrillation cycle length, and atrial electrogram morphology. [ Time Frame: Patients will be followed during the acute procedure which is expected to average 60 minutes ]
    Multistage low-energy pulses are delivered to the atria of patients while in atrial fibrillation. The atrial electrograms will be recorded and used to evaluate if there was a change in the atrial fibrillation cycle length, increased organization of the arrhythmia using frequency analysis or if the pulses were able to terminate the atrial fibrillation.
