parasystole [par″ah-sis´to-le]
a cardiac arrhythmia attributed to the interaction of two foci independently initiating cardiac impulses at different rates; it cannot be discharged by impulses of the dominant rhythm but it may be modulated by electrotonic influences. The two independent rhythms coexist but not as a result of atrioventricular block. It is an abnormality of both automaticity and impulse conduction. See also entrance block.
