Intro
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

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.
