Figure 2: Parameters used in the definition of subendocardialviability ratio (SEVR). The figure shows the pressure curvesrecorded in the left ventricle (dotted line) and in ascending aorta (continuous line). DPTI indicates diastolic pressure–time index (dark gray area); DT, diastolic time; LVET, left-ventricular ejection time; LVEDP, left-ventricular end-diastolic pressure; MDBP, mean diastolic blood pressure; MSBP, mean systolic blood pressure; and SPTI, systolic pressure–time index.
