Question

A student nurse is reviewing electrocardiograms (ECGs). Which of the following does she recognize as true about ECGs and myocardial infarctions (MIs)? Option 1: ECGs cannot detect MIs. Option 2: ECGs show abnormal electrical activity in the heart during an MI. Option 3: ECGs can only detect MIs after they have occurred. Option 4: ECGs are used to measure blood pressure during an MI.

Answer 1

Option 2: ECGs show abnormal electrical activity in the heart during an MI.

ECGs (Electrocardiograms) are indeed used to detect abnormal electrical activity in the heart, which is characteristic of various cardiac conditions, including myocardial infarctions (MIs) or heart attacks. ECGs can help identify specific changes in the heart's electrical patterns that occur when there is damage to the heart muscle, as seen in an MI. Therefore, option 2 is correct. The other options are not accurate.
