Dibutyryl cGMP, like acetylcholine, shortens and reduces repolarization and overshoot of the action potential, slightly hyperpolarizes the cell and decreases the force of the contraction in the atrial working muscle. It suggests that cGMP may mediate the action of acetylcholine in the atrial working fibres.
