Which of the following condition is associated with QRS duration greater than 0.16 seconds ?
High-Yield Explanation
Normal QRS duration: 0.06 - 0.1 seconds RAISED QRS DURATION IS SEEN IN: *Ventricular tachycardia (Assume any wide QRS-complex tachycardia is VT until proven otherwise) *Right bundle branch blocks (up to 0.14 sec) *Right bundle branch blocks with VT (> 0.14 sec) *Left bundle branch blocks (up to 0.16) *Left bundle branch blocks with VT(> 0.16) *Intraventricular block (as seen in Hyperkalemia, quinidine, procainamide) *Implanted ventricular pacemaker
