Which EKG finding is most indicative of hypertrophy in the heart?

High voltage R waves in the precordial leads are indicative of ventricular hypertrophy. When the heart muscle thickens due to conditions such as hypertension or valvular disease, it necessitates greater electrical activity to depolarize the larger muscle mass. This increased electrical activity results in taller R waves observed in the EKG readings, particularly in leads V1 to V6. A significant increase in the amplitude of the R waves is correlated with the extent of hypertrophy and is a key diagnostic criterion used to detect left or right ventricular hypertrophy.

In contrast, other options like inverted T waves might suggest ischemia or other cardiac conditions but do not specifically indicate hypertrophy. QRS complex notching can also be seen in various conditions and is not exclusive to hypertrophy, making it less definitive. A shortened PR interval is more associated with conduction disorders than with hypertrophy, further solidifying that high voltage R waves are the hallmark finding associated with hypertrophy in the heart.
