Most basic dysrhythmia instruction concentrates on the fundamentals of cardiac rhythms and the criteria that make one dysrhythmia different from another.

This article provides an overview of a few uncommon dysrhythmias (wide-QRS tachycardia, advanced atrioventricular block, sinoatrial exit block, and atrial fibrillation with complete heart block) that may be encountered when caring for patients with cardiac disorders.
