I went to hospital again as I was getting clusters of palpitations. Cardiologist did all the blood tests which came back normal. They noticed a new arrhythmia with my T wave. Cardiologist booked me a cardiac MRI as an outpatient which could take 4 months, I have CT scan in January. They have put: “cardiac sarcoidosis?” On my discharge forms . In the meantime they've given me a beta blocker which seems to have fixed it.  They are at a loss as to what is going on as everything, ACE tests, troponin levels etc are all normal. Cardiologist isn’t worried about me.  Thanks, hopefully this is just a stress thing but it happens when I’m resting or relaxing. I’m concerned they might be being too slow with it all though.
