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
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.
