In some cases, a stress test may be used to see how blood flows to that area of the heart during exertion. The Bottom Line
When the age of the infarct is undetermined, it implies that the ECG does not provide clear clues about when the infarct occurred, or the changes are not typical for a specific phase.
This refers to the front wall of the heart, specifically the left ventricle. This area is primarily supplied with blood by the Left Anterior Descending (LAD) artery—often called the "widowmaker" because it handles a large portion of the heart's pumping workload. anterior infarct ecg age undetermined
An ECG is recorded from 12 leads, which are divided into two groups: the limb leads (I, II, III, aVR, aVL, and aVF) and the precordial or chest leads (V1-V6). Each lead provides a different view of the heart's electrical activity.
Elias finally looked up, his eyes tired. "The machine’s algorithm printed 'Anterior Infarct, Age Undetermined.' Do you know what that means in English, Aris?" In some cases, a stress test may be
If this is a new finding or you have symptoms, a doctor may order an Echocardiogram (an ultrasound of the heart). This allows them to actually see the heart muscle moving. If the "anterior" wall is moving normally, the ECG finding was likely a false positive.
Aris frowned, leaning closer. "Is that... an old infarct?" This area is primarily supplied with blood by
While this reading can mean you had a silent heart attack in the past, it is not always a cause for panic. There are several reasons why an ECG might show this result:
"That’s the tragedy of 'age undetermined,' Mr. Halloway," Elias said. He pulled up a stool and sat, bringing himself to eye level. "It could have been ten years ago. It could have been last month. Sometimes, diabetes or nerve issues silence the pain. Sometimes the body is so overwhelmed by stress it misfiles the signal. You might have had a 'widow-maker' heart attack while you had the flu, and you just thought you were tired."
"Scar tissue," Elias said softly. "Dead muscle. At some point in your life, an artery clamped shut. A massive blockage. It starved a section of your heart until it died."
