Which of the following diagnostic tools is most commonly used to determine the location of myocardial damage?
a. Cardiac catherization
b. Cardiac enzymes
c. Echocardiogram
d. Electrocardiogram (ECG)
Ans: d. Electrocardiogram (ECG)
The ECG is the quickest, most accurate, and most widely used tool to determine the location of myocardial infarction. Cardiac enzymes are used to diagnose MI but can't determine the location. An echocardiogram is used most widely to view myocardial wall function after an MI has been diagnosed. Cardiac catherization is an invasive study for determining coronary artery disease and may also indicate the location of myocardial damage, but the study may not be performed immediately.
