Question

Quizplus · Accepted Answer

In left ventricular hypertrophy, the heart muscle of the left ventricle thickens, which means there's more muscle mass for the electrical current to travel through. This results in QRS complexes on an ECG that are taller and deeper than normal, reflecting the increased electrical activity required to depolarize the enlarged heart muscle.
