Question

Mr. Smith is telling his friend about his recent visit to his doctor for a checkup. During his story, he mentions that the ECG reveled that he had a defective mitral valve and a heart murmur. Mr. Smith apparently misunderstood some of what the doctor explained to him about the diagnostic process. What has he misunderstood?

Answer 1

An ECG, or electrocardiogram, does not reveal information about heart valves.

Most likely, he meant an echocardiogram.
