[QUOTE=BonBon;3307417]A heart murmur has been added to Chelsea's list of issues.
I took her in earlier this week for the follow-up ECG and the doctor gave her a referral to a specialist. We couldn't get in to see them this week so my vet wanted to go ahead and do another ECG this morning. Afterwards he took a heart x-ray, which appeared normal thank God. He'll be sending the x-ray to the specialist digitally so Chelsea shouldn't need another one.
We saw a different Dr. this morning (Dr. Haynes is on vacation all this next week). When Dr. Yeagley listened to Chelsea's heart he said he definitely detected a murmur. Given the tests that have been done so far, he's listing Chelsea's preliminary diagnosis as Structural Heart Disease.

He refused to give me a prognosis, which I can understand. I just hate the waiting and not knowing!!!"
I think it might be possible two seperate issues your dealing with here. Perhaps a SA node conduction problem therefore the decreased heart rate.
Then with the murmur a valve, what kind of murmur did he hear, diastolic vs systolic, in what area of the heart heard. Mitral valve murmur and then tricuspid valve, aortic valve, then last pulmonic valve.
I know your running on overload atm. So sorry your in my prayers daily with Chelsea. I want to give you a great big hug and a shoulder to lean on!
I apologize for the overload of info, my nursing kicking in. All you need is for your baby to feel better and be happy.
Thinking of you both sending strength to you with blessings to Chelsea
