Dusty has had a heart murmer for years. Hers was found when she was about 6 yrs old, they said not to worry about it, that it was mild. When she was 7 she developed aspiration pnemonia and among the things they did was an EKG, they also found the murmer, but agreed that it was mild and just to keep an eye, or rather, ear on it.
A few years ago we got a new EKG machine in at work and needed 'test subjects', needless to say I voulunteered Dusty. It took several different leads before we finally found the murmer, and the dr. confirmed that it was a very mild and needed no treatment. (BTW my uncle has also had a murmer since he was a boy and never needed treatment).
Dusty is now 16 1/2 and her murmer still isn't a problem for her.
Also they shouldn't need to put your cat out all the way, a light tranquilizer should be sufficient for an EKG (I couldn't tell you on an ultrasound as we don't have one of those at work). We only tranquilized Dusty for the EKG we did, we didn't put her all the way out. (BTW we didn't tranq. her just for the EKG, she was also in for a dentistry at the time and required the tranq. anyways.)
If it were my cat I'd probably ask the vet if he/she thought an EKG was even warrented, and if so that would probably be my route if they could just tranquilize rather than put the cat all the way out.
Is there something that makes your vet suspect a tumor?
