Question

Myocardial ischemia may result in:

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

Answer 1

Myocardial ischemia can cause ST segment depression and inverted T waves on an electrocardiogram (ECG), indicating reduced oxygen supply to the heart and potential cardiac damage.

Step-by-step explanation:

Myocardial ischemia refers to the inadequate blood supply to the heart muscle, often caused by a blockage in the coronary arteries. This lack of blood flow can result in certain changes on an electrocardiogram (ECG). Specifically, myocardial ischemia may lead to ST segment depression and inverted T waves. These ECG abnormalities can indicate reduced oxygen supply to the heart and potential cardiac damage.
