Answer 19

19.  Answer B is the correct answer.  With left ventricular hypertrophy, the QRS complexes become bigger in height and depth in leads V1-V6.  The S wave will be even deeper in V1.  The largest R wave will be in lead V5 because it lays over the left ventricle.  The T wave will often be inverted or cause asymmetry.  With right ventricular hypertrophy, there is large R wave in lead V1, there is amore positive deflection toward the V1 electrode and the QRS complex more upright than nomad.  The R wave gets progressively smaller in leads V2-V6.  With right atrial hypertrophy, the P wave is affected.
