Customer Question

My cavalier is 13 years old. He as kidney issues 30/278, he has heart murmur level 4,
chronic bronchitis, he has consistent tremors. He had a stroke a few years ago, which I believe is rare.
Jack has convulsions, they are getting more consistent 2 to 3 a day, my Vet thinks its due
to his heart rate going from 120 to around 250 at intervals. We have just started him on lanoxin meds. He does not have fluid on the lungs.
OK, my question is over the last few weeks when he lies down he immediately sits up again and will sit or stand for very long periods, where as before he would lay down and snooze a lot, he seems to be agitated as well. My Vet is not available at present and am concerned I am not doing the right thing by our little boy.
Thank you

Hello, thanks for your question today! I am Dr. Drew, and I am a licensed veterinarian. I'll be happy to help you in any way I can.
I am sorry to hear about Jack's condition. Your description sounds very much like the classic signs of Congestive Heart Failure, even though you mentioned "He does not have fluid on the lungs". Patients with congestive heart failure develop what's known as "orthopnea", which is positional difficulty in breathing, so that laying down results in an inability to comfortably get enough oxygen. This leads to restlessness and a standing / sitting posture being necessary for comfort and adequate oxygen transfer.
I would strongly recommend having chest x-rays done today, along with a thorough physical examination and auscultation (listening to the lungs).
The rapid change in heart rate suggests that Jack's heart muscle may be failing at a rapid rate, and therefore an Echocardiogram also may be a wise idea.
