What EKG findings are expected in a patient with hypertrophic cardiomyopathy?

In hypertrophic cardiomyopathy (HCM), the expected EKG findings primarily include left ventricular hypertrophy (LVH) and associated repolarization abnormalities. The increased muscle mass of the heart results in a higher voltage in the leads that correspond to the left ventricle, which is consistent with the criteria for diagnosing LVH on an EKG. Furthermore, repolarization changes may manifest as downsloping ST segments and T-wave inversions, especially in the lateral leads, indicating that there is strain on the heart muscle due to the hypertrophy.

While wide QRS complexes can sometimes be seen in other conditions or in patients with significant conduction system disease, they are not characteristic of hypertrophic cardiomyopathy itself. ST elevation in lateral leads is more indicative of acute myocardial ischemia or injury rather than the structural changes associated with HCM. Lastly, a short QT interval is not a typical finding in hypertrophic cardiomyopathy; rather, it can be associated with other conditions.

Thus, the findings of left ventricular hypertrophy alongside repolarization changes make option B the correct choice when evaluating the EKG in patients with hypertrophic cardiomyopathy.
