"A worrying wait"

What could be improved

I was referred to the cardiology department by my GP and had a 24 hour ECG monitor fitted, I was contacted by my doctor 2 weeks later asking me to come and see him the same afternoon, excellent service, he explained the results of the ECG and told me I needed to have further tests including an echocardiogram urgently, I logged on to choose and book only to find that the earliest urgent appointment was in mid July so another 6 weeks of worry so I phoned them to be told to keep checking the website daily for earlier cancelled appointments or contact my GP, I did this and now my very busy GP has to write a letter to the cardiology department to try for an earlier appointment, I appreciate their may be patients with more urgent needs but am a bit disappointed.
