ATRIOVENTRICULAR DISSOCIATION

Any situation in which atria and ventricles are activated and contract independently, as in complete A-V block, more specifically, the dissociation between atria and ventricles that results from slowing of the atrial pacemaker or acceleration of the ventricular pacemaker at almost equal (rarely equal) rates, every depolarising its own chamber, thus interfering with depolarisation by the another (interference-dissociation).
