Table 1.

Wall motion score index (WMSI), Err, ejection fraction (EF) and end-diastolic left-ventricular pressure (EDLVP) in five dogs under graded myocardial ischemia. WMSI was assessed with 5: Normal; 4: Mild hypokinetic; 3: Hypokinetic; 2: Severe hypokinetic; 1: Akinetic; 0: Dyskinetic. Err denotes the ME end-systolic radial strain.
