Abnormal EKG
An_243926 posted:
Can an Ekg machine malfunction? During a doctors visit an ekg was done upon request. Ekg results showed I was having an acute Myocardial infarction . Leads were never moved but 5 tests were taken all showing the same result.
James Beckerman, MD, FACC responded:
The computer that reads your ECG is sometimes wrong. There are sometimes situations in which the computer interprets the findings as being consistent with having a heart attack - but that's why it's important for a doctor to be taking a look too!
cardiostarusa1 responded:

It's possible (as anything electrical/electronic can), and adding to what Dr. Beckerman said -

Good general info



It is important to remember that EKGs are not 100% accurate. Normal recordings can be obtained in patients with significant heart disease, or some "abnormalities" may exist in the presence of a normal heart.

Additionally here, of the different types/kinds of heart conditions, various symptoms may/can be acute (occurring suddenly), be chronic (occurring over a long period of time), come and go (be transient, fleeting or episodic) or even be silent (no telltale symptoms).

Be well-informed

Imaging Ischemia or a Heart Attack (myocardial infarction, MI, actual death or necrosis of heart muscle/tissue/cells)

Isotope/Nuclear Stress Test

SEE: Actual rest/stress nuclear images

The physician can separate a normal left ventricle, from ischemia (live muscle with flow that is compromised only during exercise) and the scar tissue of a heart attack......

Be a questioning patient. Talk to your doctor and ask questions. Studies show that patients who ask the most questions, and are most assertive, get the best results. Be vigilant and speak up!"
