  1. Healthy cat ranges (median [interquartile range]) were established from 15 healthy cats
  2. AP apical level, LV left ventricular, MV mitral valve level, PM papillary muscle level, RV right ventricular, SC circumferential strain, SL longitudinal strain, SrC circumferential strain rate, SrL longitudinal strain rate
  3. aValue that was out of the interquartile range of the 15 healthy cats
