An example of idioventricular rhythm

In idioventricular rhythm the rate is 30-45 bpm. The QRS complexes are wide (> 0.12 sec, often > 0.16 sec) because the ventricular signal is transmitted by cell-to-cell conduction between cardiomyocytes and not by the conduction system.

Accelerated idioventricuar rhythm is a rapid form (60-120 bpm) of idioventricular rhythm associated with reperfusion during myocardial infarction.
