Interpretation
The small number of ventricular arrhythmias noted could be found in some normal animals. I see no definitive
Holter contraindication for breeding this patient. If the owner wishes to more definitively rule out structural heart
disease in patient prior to considering breeding, an echocardiogram may be considered (this breed is predisposed
to dilated cardiomyopathy). A recheck Holter should be considered in 6 - 12 months to continue to rule out
cardiomyopathy in this patient
Our comments and plans: Echo was done on Lacy in Sept 08. This is very good news our plans now are to rid
Lacy of the Lyme she is currently being treated for and make plans to have her hip and elbows OFA certified. If
there are no other problems we will plan on Lacy to be bred in Aug/Sept this year. Check back for the results of
Lacy's OFA work up on Elbows and Hips.

On Tues & Wed. Feb 24 & 25 Lacy had her follow-up work done. On the 24th we had the Serum Chemistry done
for Tick born diseases. She also had the 24 hour Holter test done. In preparation of the test Lacy had two areas
shaved down to the skin to attach electrodes that would record her heart activity for a 24 hour period. During this
period we also kept a journal of her activities such as play, eating and sleeping. We got the results back for Tick
diseases Thursday the 26th. Not good news...Lacy still has Lyme but now worse. Apparently we did not treat her
Lyme aggressively enough the first time and it only got worse. Friday the 27th Lacy was put back on the
Doxycycline for 6 weeks which will end near or at the time she would be do to come in season. We are not going
Lacy at all. Click here to see pictures taken of Lacy getting the Halter put on and then waiting in the lobby next
day to remove the halter.

On the 3rd of October Lacy had an Electrocardiogram exam, 6th of October results were in and not as good as we
had hoped. Lacy's electrocardiogram demonstrated a normal sinus arrhythmia at a rate of 136-171 beats per
minute. Approximately 20 isolated atrial premature complexes were noted per minute. Arrhythmia noted can occur
as a result of atrial enlargement and may be associated with early /occult dilated cardiomyopathy (though this was
not noted on echocardiography) done on the 24th of September. Other causes of arrhythmia such as atrial
myocarditis (idiopathic or rickettsial) is possible. Two additional test were recommended to help determine the
underlying cause and to assess her condition before breeding. The first of two recommended procedures. A
CBC and serum chemistry analysis. The results of that test came back on Thursday the 9th of Oct. Results
showed Lacy to be borderline positive for Lyme disease. Friday the 10th of Oct, Lacy was started on Doxycycline
600 Mg a day for 28 days. Up until Friday night Lacy never exhibited any symptoms of Lyme. That evening Lacy
went lame in her right rear leg and refused to bare any weight on it up until Saturday evening. In addition to her
Doxycycline she will be given 340 mg of Previcox for pain as needed. After 28 days or shortly there after we will
follow-up with another CBC and tick panel analysis. If Lacy is found to no longer have the Lyme bacterium
present. We will proceed to the 2nd recommended procedure - the halter test. The holter monitor is
recommended to assess the presence of arrhythmias in a 24 hour period. After this last procedure we will know if
our plans to breed Lacy will go on as scheduled or canceled. As for our feelings on this. Nothing is more
important to us than the health and well being of our hounds. When you breed regardless of what breed there is
always a risk of unforeseen problems. However we will not knowingly put Lacy in harms reach and we will cancel
our plans to breed her if the risk is now too great. If we do proceed with our plans to bred Lacy, we will have plans
in place to monitor her pregnancy very closely. Please check back to get updates on Lacy's progress.

Lacy went to see Larry Nafe DVM at Hillcrest Animal Hospital in Little Rock, Arkansas for her most important
per-screening exams an Echocardiogram a very specialized cardiovascular procedure used to assess the heart's
function and structures. Lacy did very well, exam results were very good. Oct 3, Lacy will also have a
Electrocardiogram done to make sure we cover all the bases. This exam records the electrical activity of the
heart. Oct, 13 Lacy is scheduled to have her hip and elbows x-rayed for OFA review.
