Question

Quizplus · Accepted Answer

ST segment depression and T wave inversion are classic indicators of myocardial ischemia on an ECG. Pathologic Q waves and ST segment elevation can be indicative of a previous myocardial infarction. Positively deflected T waves and physiologic Q waves are typically non-specific and not indicators of ischemia. Wide QRS complex and absent P waves can indicate other cardiac issues like ventricular tachycardia or complete heart block, but not necessarily ischemia.
