What is a defining feature of a Wide QRS complex?

A defining feature of a Wide QRS complex is that it has a duration of more than 0.12 seconds. This characteristic indicates a delay in the conduction of electrical impulses through the ventricles of the heart. When the QRS complex exceeds this duration, it typically suggests that there is an underlying issue with the heart's conduction pathways, such as a bundle branch block or ventricular rhythm.

Understanding the duration of the QRS complex is crucial for clinicians as it helps in diagnosing various cardiac conditions. The normal QRS duration is typically less than 0.12 seconds, and significant deviations from this range can inform healthcare providers about potential dysrhythmias or structural heart issues.
