Re: (OT for CRF) irregular heart rhythm
Unfortunately, an irregular heart beat can be a sign of many things.
The actually rhythm cannot be identified unless an ECG, an
electrocardiogram, is done. And the kitty must be in the rhythm at the
time that the ECG is done. I would have the work up done and consider
having an echocardiogram done. An ECG can only give you a picture of
the electrical activity of the heart and a general idea about enlargement,
but cannot tell you about its function. An echo can determine any
enlargement or restriction that is present.

- I would also check thyroid since it's one of the most basic "fuels"
that regulates SO much of our, and our kitties, metabolism. At her
follow up visit I mentioned to the vet (they have 4 in this practice, 1
is cardio) that her pupils had been frequently uneven. Her last vet
just chalked it up to aging process. Now that she's on hyper-t meds, I
haven't seen it. This vet wasn't even remotely surprised that they are
now behaving in unison.
Abby, I suspect, has been having thyroid issues for probably half of
her 14 years. Since late February I have thought a lot about her, her
problems, and about when they seem to have started. She started getting
the classic bald patches of thyroid at (near as I can figure) around 7
years old. I knew in 2002 she had an enlarged heart, something that
doesn't happen overnight. My gut feeling is the two are related.
I am not certain I can place *all* the blame for her current situation
on her former ve. I do feel he should have treated a senior kitty more
aggressively. It wasn't because I was giving off any "save me money"
signals. Whatever she needed she got, there was never any questioning.
There was another vet that she went to for 10 years. Could he have
treated earlier? Probably.
What I do know now is that should I see anything, including an apparent
"asymptomatic" heart issue, I will be placing my foot *firmly* on the
ground and insisting on treatment to halt further progression of
disease. I also now know that thyroid can cause all sorts of wacky
While she seems pretty "floppy" to me now, she in many ways behaves
like other felines I have shared my life with. I suspect she's 'normal'
now, whatever that is! <g>

- Hi, Jen.
Thank you for the feedback.
I took Tina (and Celeste) to the hospital on Sunday (this is a different
hospital where I take Don who is hyperthyroid, hypertensive, and CRF). As
expected, Tina's heartbeat was back to normal and the vet in attendance
didn't have any idea (or maybe she had never heard of such a phenomenon) as
to what is causing Tina's heartbeat to go out of rhythm from time to time. I
described Tina's sort of occasional hyperactivity and she too suspected
hyperthyroidism. So, we did a senior wellness profile that includes CBC,
chemistry, thyroid, and urinalysis (and heartworm antibody) for both Tina
and Celeste (Celeste is also 13.5 years old; they both don't have any
apparent symptoms, just getting older).
Tina is not hyperthyroid. Her T4 was 0.78 (range 0.8-4.0). Her BUN was 42
(14-36, HIGH) and creatinine was 2.4 (0.6-2.4). Phosphorus was 6.4 (2.4-8.2)
which is high for her age. These numbers seem to indicate early CRF, but her
urine specific gravity was 1.062 (1.015-1.060, HIGH) and she had some
protein (2+ HIGH) in her urine. The vet thinks her kidney function is
getting insufficient and wants to check again in three to six months.
A member in CRF group mentioned about paroxysmal atrial tachycardia. This
sound very much like what Tina is exhibiting. She also mentioned that it
might be difficult to make a diagnosis because of the transient nature of
the phenomenon. So far, Tina's heartbeat has been normal since Sunday and
she is behaving normal in all aspects.
I am thinking about taking her to Don's vet who is an IM specialist for
further examination as well as a consultation on her kidney issue (high
kidney numbers with concentrated urine?). There is a cardiologist at her
hospital and they can do an echocardiogram and blood pressure measurement,
By the way, Celeste's values were quite normal except for:
Total protein - 10.1 (5.2-8.8) HIGH
Globulin ------ 7.2 (2.3-5.3) HIGH
CPK ----------- 805 (56-529) HIGH
Triglyceride -- 271 (25-160) HIGH
I guess I'm asking Don's vet about these, too.
Thank you again.
