ECG machine

Hello,
Welcome to the ehealthforum and I am really glad to help you out. It is not possible to tamper the ECG machine in such a way that it shows a normal ECG in a cardiac patient with abnormal heart.

I sincerely hope that helps. Take care.

Here is the problem. Two things are for sure: a person is gravelly ill and the cardiograms do come out perfectly normal. So, the question is how do they do it? I happen to have two cardiograms. One normal and one abnormal.

Would it be possible for you to look at those cardiograms and to answer the following question: could it to be possible that those two cardiograms were produced by the same heart approximately at the same time (not necessarily on the same day)?

Suppose you have a gravely ill cardiac patient and you want to deceive him by printing perfectly normal cardiogram with his name printed, and actual date and time of the test. I presume that this can done by prerecording a normal cardiogram on the hard drive and instead of printing what is on the screen, to recall it from the hard drive, attach patient's name, date and time to the recalled picture and print it. Any comments on that?

Should I presume you have nothing to say?
