When trying to do an ECG the wave lines are all the way to the top to the bottom of the graph every 1 millimetre or so any ideas what's wrong as it doesn't take a reading only lasts 5 seconds nit the full 30 before stopping?
Probably thinks your on a treadmill making the graph go all over the place!. Try to lie or stay still, I have loads done at the hospital and I'm always told to relax so they can get a proper reading.
