Heartbeats

Okay...so Graham's heart rhythm has changed again...it seems almost normal...but is "normal" good?! I talked to the cardiologist today and he said not to panic that all was okay. He is trying to bump up Graham's test (he was on hold due to the isotope shortage) so I am to call him on Friday if I don't hear anything. It's not the cardiology clinic that books the test, it's radiology, we are spoiled in the cardiology dept. AGH!!
