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.
