1. A method of treating a heart in need of atrial defibrillation comprising the steps of:

  • (a) determining an atrial fibrillation cycle length (AFCL) of a heart suffering from a fibrillating atrium;

    (b) sequentially delivering a plurality of synchronous pulses of electrical current to a plurality of different atrial sites at a uniform pulse-to-pulse interval rate selected to be a common percentage value of said AFCL;

    (c) determining whether atrial defibrillation is achieved; and

    (d) where atrial defibrillation is not determined in step (c), repeating steps (a), (b) and (c) one or more times until atrial defibrillation is achieved.
