I am not a Doctor and would recommend that you see one. But, you can buy a ECG monitor for around 100 to 200 dollars and record the ECGs yourself and use your computer to print out or e-mail the results to your doctor. I use one called PC-80B Easy ECG Monitor. It can do 30 second quick checks and about 9 hours checks using 3 wires it comes with. It does fine when you are sleeping or not moving but when you are moving, even stretching in Bed you will see what medical folks call artifacts. They are just errors in reading so don’t freak out when you see something odd since if my very well be an artifact. That is why you would want your doctor to look at the output. I bought a book to learn to read the ECG and I know enough to know when I am in rhythm or am having PACs, PVCs or AFIB, but I learned enough to know that the interpretation of ECGs for complex heart problems needs to be left to folks that do it for a living. I am told by my doctor that the halter monitors are not much better than mine. I think the 12 lead ECG they use when you are in the hospital are much better and provide many more views of your heart so they can detect more problems.
