Idioventricular Rhythm

This is part of: Supraventricular Rhythms

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.
