Hypertrophy refers to an abnormal thickening of a chamber wall.

Simply put, this abnormal thickening translates to an increase in the voltage of the QRS complex.

The wall thickens due to increased vascular resistance over time

heart with left ventricular hypertrophy

Intro 2

QRS complexes will show greater amplitude (more muscle mass = more electrical activity)

Taller and deeper ventricular depolarization waves will be seen

Remember: Hypertrophy increases voltage – BBB increases duration.
