The nurse is admitting a patient with complaints of dyspnea on exertion and fatigue. The patient's ECG shows dysrhythmias that are sometimes associated with left ventricular hypertrophy
What diagnostic tool would be most helpful in diagnosing cardiomyopathy?
A) Cardiac catheterization
B) Arterial blood gases
C) Echocardiogram
D) Exercise stress test
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 is also important, and can demonstrate dysrhythmias and changes consistent with left ventricular hypertrophy. Cardiac catheterization specifically addresses coronary artery function and arterial blood gases evaluate gas exchange and acid balance. Stress testing is not normally used to differentiate cardiomyopathy from other cardiac pathologies.
