Ventricular hypertrophy or conduction delay

Vedclass · Answer

(B) The $QRS$ complex represents the depolarization of the ventricles,which initiates ventricular contraction.In a normal $ECG$,the duration of the $QRS$ complex is typically less than $0.12$ seconds.If the time taken for the $QRS$ complex is higher (prolonged),it indicates a delay in the conduction of electrical impulses through the ventricles.This is often associated with conditions such as ventricular hypertrophy (enlargement of the heart muscle) or bundle branch blocks,where the electrical signal takes longer to spread through the ventricular myocardium.
