<< I think even now, there are ECG machines which can identify if the ECG is normal/abnormal and can print the interpretation itself!!!

A colleague of mine went for his ECG at Heathrow and after a minute or so the nurse said "Well, Mr X, according to this you are dead"!!
During one of my medicals the Doc told me that the distance between the vertical lines can indicate how clogged your arteries are. This is backed up by another medic who asked another colleague if his wife did all the cooking.. "yes, she does".... "well, telling her she's killing you!"
