Can you explain left ventricular hypertrophy?

LVH: Left ventricular hypertrophy is when the muscular walls of the left ventricle are thicker than normal. The left ventricle hypertrophies when it does excess pressure or volume work. It can also thicken genetically or when infiltrated by some other form of cells. By far the most common causes are high blood pressure and excellent physical conditioning from long term exercise.
