An EKG can reveal if your heart is getting enough oxygen.
However, due to blockages or constrictions in the coronary blood vessels, the heart can experience ischemia, a dangerous state in which the cardiac tissue is underperfused.
Will an EKG show heart problems?
Electrocardiogram (ECG or EKG) to assess the heart rate and rhythm. This test can often detect heart disease, heart attack, an enlarged heart, or abnormal heart rhythms that may cause heart failure.
Can an ECG detect a blocked artery?
An ECG Can Recognize the Signs of Blocked Arteries.
Unfortunately, the accuracy of diagnosing blocked arteries further from the heart when using an ECG decrease, so your cardiologist may recommend an ultrasound, which is a non-invasive test, like a carotid ultrasound, to check for blockages in the extremities or neck.
