Take it very easy and don't drive. You do need to have that stress ECG done because you just might have unstable angina and that does not show up on a resting ECG.
Please DON'T drive, but it sounds good to be back home and with your wife. Arrange for medical records transfer to your home doctor.
Could you take a bus, train or fly?
Or, (you've a car?) Could a family member come (bus, train, plane) fetch you and drive you home?
