1. An ablation system, comprising: an ablation catheter having at least two flexible ablation elements; at least one electrode affixed to each ablation element reading at least one of ECG and EKG information, and transmitting energy to tissue in a monopolar mode, a bipolar mode, and a combination monopolar-bipolar mode; an interface unit coupled with the ablation catheter including a control interface and a visual display; the visual display having a graphic representation of the ablation elements, the electrodes, an electrical signal from each electrode, an indication of whether each electrode is selected to transmit energy, a current quantitative representation of a system parameter, a system parameter target value, and an indication of the selected energy mode.
