Wide complex refers to a QRS duration exceeding 120 milliseconds on an electrocardiogram, indicating delayed ventricular depolarisation. Clinically, it suggests abnormal conduction through the ventricles, often due to bundle branch block or ventricular tachycardia, which requires urgent evaluation. Recognising wide complex rhythms is critical to differentiate life-threatening arrhythmias from benign causes.
