Parasystole is the phenomenon that results from two competing pacemakers in the heart. Usually a supraventricular and nodal / ventricularnormal pacemaker compete. For example sinusrhythm interfered by ventricular ectopic beats. The basic rhythm in this example would be sinusrhythm with e.g. a rate of 60/min. Interfering with this rate ectopic ventricular beats can be seen. Parasystole is diagnosed when the ectopic beats have a constant RR interval, e.g. 1500ms, resulting in a rate of 20 ventricular ectopic beats per minute. [[Fusion beats]] are often present as the two rhythms are dissociated. | Parasystole is the phenomenon that results from two competing pacemakers in the heart.
