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.

How long after a heart attack can it be detected?

Within the first few hours of a heart attack, though, both the troponin level and the electrocardiogram can be normal. That means people with results in the gray zone are observed and monitored for 12 to 16 hours with more troponin tests and electrocardiograms.
