Abstract
An apparatus for treating atrial fibrillation or atrial tachycardia comprises means for dynamically steering or selecting two or more current vector paths sequentially or simultaneously for defibrillation to change the transmembrane potential in the left and right atria sufficiently to halt AF or AT. The apparatus is useful to treat AF or AT in patients.

A method for treating atrial fibrillation or atrial tachycardia, which comprises dynamically steering or selecting two or more current vector paths sequentially or simultaneously for defibrillation to change the transmembrane potential in the left and right atria sufficiently to halt AF or AT.
A method for treating atrial fibrillation or atrial tachycardia, which comprises delivering biphasic ascending or descending exponential, ramp, or damped sinusoidal waveform which are most efficient with respect to the transmembrane potential response within the myocardium by use of an amplifier array where any two, three, or four amplifiers and their respective electrodes may be driven differentially as to draw current through selected current pathways or different angular perspectives within the right and left atria to rapidly terminate AF and AT.
