Hi- this is a patient f/s 10yr old border collie. two years ago we diagnosed myocarditis. she was successfully treated with pred. she is maintained on mexiletine and sotalol for a severe arrhythmia . she is well controlled but lives with first degree av block. even with her first echo we had increased lvdd ,lvds but poor alignment on m-mode. so difficult to interpret. we had cardiolgy consult early on. i have followed her every 6 mnths the lvds lvdd remains about same.i picked up a small mr jet on this visit. my question is should i be using another means to evaluate systolic ftn?

Hi!
To me it seems like the systolic function is not markedly impaired, even though systolic diameters are slightly out of the reference range (28 mm).
You could use EPSS or Volumes (Simpson`s method of discs).
Usually, if systolic function is chronically impaired, the ventricle will enlarge (as with DCM).
If the first degree AV-block is vagally mediated (resolves with Atropin or stress), systolic function can as well be affected by the increased vagal tone (low heart rate, low systolic function).
Best regards and thanks for posting!

Thanks very much–the epss
Thanks very much–the epss has been very slightly increased but also doesn’t change.That’s what I needed to know. she’s doing fantastic clinically!!!
