An ECG provides information about the wearer of the ECG's heartrate and rhythm of the heart. It provides information about wether it is normal or abnormal.

No, it doesnt.
ECG gives information about the rate, rhythm, and information about conduction of nerve impulses in the heart, evidence of damage to the heart from poor blood supply or previous heart attack, and of course changes to suggest recent heart attack. It is therefore useful to diagnose atrial flutter, fibrillation, heart block, ischaemic changes and heart attack
The E.C.G will not confirm a heart attack it only gives you a reading.
Yes, it is appearently possible.
