I have a heart murmor, the surgeon and anesthetist required me to have an ecg and an echocardiogram before i could go ahead (luckily i had just had my 5 year check up a few months beforehand so already had these tests done). Its all up to the aneasthetist as to wether he will put you under aneasthetic, i had to wait until 2 weeks before my op before i got a desicion as they had to wait for rota to come out to see what aneasthetist would be working on me x
