ECG and Heart Disease

How to interpret ECG and say that the individual is likely to get heart attack?

[kenkeith]

An EKG (ECG) isn't a very could source for a prognoses.  A CT angiogram scans the anatomy of the coronary vessels and scores the amount of soft plaque within the linings of the vessel.  Based on the score there is a predicition of the risk to the individuals to a heart attack.  The soft plaque is the condition that poses the highest risk of a heart attack as the soft plaque can break through the inner lining of the vessel and cause a blockage that results in heart attack.  

An EKG can with some reliabilty can determine if there has been a heart attack.  If there has been prior heart attack and scar tissue, the electrical impulse will not properly conduct through the scar tissue and that will provide a wave form on the EKG output.  The st segment on the EKG output is the segment of interest.

Also, a different configuration of the st segment can indicate an enlarged heart and that could cause a future heart attack.  An enlarged heart requires more time for the electrical impulse, etc. to pass through the heart tissue.

Hope this provides a perspective of use for you.  Thanks for the question, and you are welcome to respond with any other questions you may have.  Take care.
