Wide QRS complexes indicate which type of rhythm?

Explanation:
QRS width shows how the ventricles are activated. A narrow QRS, typically under 120 ms, means the impulse uses the normal His-Purkinje system and the rhythm is supraventricular in origin (such as atrial, junctional, or sinus). When the QRS is wide (over 120 ms), ventricular activation is starting within the ventricles or is conducted abnormally, so the rhythm is ventricular in origin. In telemetry, wide QRS complexes are most consistent with a ventricular rhythm, such as ventricular tachycardia, though some supraventricular rhythms with aberrant conduction can also appear wide. So, wide QRS complexes indicate a ventricular rhythm.
