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?
