What is typically seen on an EKG in cases of hypertrophic cardiomyopathy?

In cases of hypertrophic cardiomyopathy, the most notable finding on an EKG is left ventricular hypertrophy (LVH). This condition is characterized by an abnormal thickening of the heart muscle, particularly in the left ventricle, which leads to distinctive changes on the electrocardiogram.

LVH can manifest on an EKG as increased voltage in the QRS complexes, particularly in the leads that face the left ventricle (such as V5 and V6) and the precordial leads. This hypertrophy affects the myocardial cells and results in larger electrical signals due to the increased mass. The presence of LVH can also be associated with other abnormalities, such as repolarization changes.

The other potential findings noted in the incorrect options do not typically represent the classic EKG changes seen in hypertrophic cardiomyopathy. For instance, a prolonged QT interval is more associated with conditions such as long QT syndrome and is not characteristic of hypertrophic cardiomyopathy. Right axis deviation may suggest other forms of heart disease or conduction abnormalities but is not specifically indicative of hypertrophic cardiomyopathy. ST elevation is often seen in conditions such as myocardial infarction rather than in hypertrophic cardiomyopathy itself.
