I would strongly suggest you talk to your Dr. if he is the same as the one your work for your in the right place.
Doing tests on each other can cause lots of problems as the test is stored in the system and if you do have something wrong you did not obtain a Medical Drs. opinion to perform the ECG or have a professional read it and write a report.
We often get into problems when we start testing ourselves. I know as I have seen this happen with some of my medical staff.
Kindly,
