Question

Quizplus · Accepted Answer

Q waves develop in the electrocardiogram (ECG) following myocardial infarction (MI), which signifies the death of cardiac muscle fibers due to ischemia. Q waves represent the absence of electrical activity during the QRS complex in ECG leads facing the myocardial infarction. Q waves in II, III, and aVF leads typically indicate an inferior MI. These Q waves usually persist for a long time, even several years, and can serve as evidence of a past MI. Therefore, the statement is true.
