B) ST segment depression.
C) QRS duration greater than 0.12 seconds.
D) inverted P waves.

Question

Quizplus · Accepted Answer

Myocardial ischemia can cause a decrease in blood flow to the heart muscle, leading to changes on an electrocardiogram (ECG). ST segment depression is a common finding in ischemia, as it represents an abnormality in ventricular repolarization due to reduced blood supply. J waves (also known as Osborn waves) are typically seen in hypothermia, but may also occur in ischemia. QRS duration greater than 0.12 seconds may indicate conduction abnormalities, but is not specific to ischemia. Inverted P waves may suggest atrial abnormalities, but are also not specific to ischemia.
