What diagnostic tool would be the most helpful in diagnosing cardiomyopathy?
A) Cardiac catheterization
B) Arterial blood gases
C) Echocardiogram

Ans: C
Feedback: The echocardiogram is one of the most helpful diagnostic tools because the structure and function of the ventricles can be observed easily. The ECG demonstrated dysrhythmias and changes consistent with left ventricular hypertrophy. Cardiac catheterization, arterial blood gases, and Swan-Ganz analysis would not be helpful in diagnosing cardiomyopathy.
