The vet can check to see if that is the cause
of the irregular beat. An EKG (ECG) will tell
but really bad ones can be told just by listening.
You can read about this in an old compilation in
the FHL Files section or by using the FHL Archives,
and even you read the compilation you should use
the archives for later info.
Look for posts containing phrases like
"Heart Node Block"
"A/V Node Block"
The atria and the ventricles wind up with different
rhythms and pacing due to damage to the electrical
There are 4 categories of Node Block. Level 1 often
does not need treatment, and may remain Level 1
forever or may worsen. Level 2 needs treatment
and with treatment can be survived for years; it
may worsen or may remain a Level 2. Level 2
Sinus is a worse form of Level 2 and always worsens.
How long those ferrets last with treatment depends
on how rapidly it becomes a Level 3. Level 3 is
Complete A/V Node Block. With treatment a ferret
can last months unless there have been major
medication advances. We had one go 9 months with
along with insulinoma in a portion of the pancreas
that can not have surgery, and were told that was
more than normally would have been expected.
So, the vet needs to find out what type and (if
applicable) what level of rhythm problem exists.
We've also seen ventricular arrhythmia with
dilated cardiomyopathy and that ferret responded
beautifully to Digoxin. In fact, she went about a
year and and half with her heart disease, even
though she was at risk of immediate death at any
time before the ventricular rhythm could be improved.
She was having a lot of bigeminis and even some
trigeminis -- very serious condition. For this sort of
heart problem chest x-ray, EKG, and ultrasound are
Of course, with A/V Node Block an ultrasound
and sometime x-ray also wind up important in the
medication protocol design.
Sometimes a seizure can cause a temporary atrial
arrhythmia in other species so maybe it can in
ferrets. I don't know if one can cause a temporary
