  1. Healthy cat ranges (median [interquartile range]) were established from 15 healthy cats
  2. A Late-diastolic trans-mitral flow velocity, E Early-diastolic trans-mitral flow velocity, E’ myocardial velocity of the septal mitral annulus at early-diastole, IVS interventricular septum, LA left atrium, LV left ventricular, S’ myocardial velocity of the septal mitral annulus at systole
  3. aValue that was out of the interquartile range of the 15 healthy cats
