I had a cardiology appointment last week (telephone) on the 1st and the cardiologist said he would refer me for an MRI of my heart and for a 48 hour monitor of my heart. On monday the 5th I got a text saying that my gp had referred me for an echocardiogram and a 24 hour hear monitor thing. So I called them as I had a conflicting appointment that day (nothing to do with cardiology) and it turns out that this appointment for tomorrow is from my GP made in May. I've told them to cancel it as the information they have is probably not up to date and now I'm thinking, should I just go to the appointment requested by the GP in May or should I wait for the tests the Cardiologist requested?
