^ǂ

Corrected for rate pressure product; heterogenity index = MBF_MAX/MBF_MIN; TPG = MBF_ENDOCARDIUM/EF, ejection fraction; MBF_EPICARDIUM; MVO₂, myocardial oxygen consumption; MEE, myocardial external efficiency; LV, left ventricle; NSVT, nonsustained ventricular tachycardia; TG, transmural gradient; RI, retention index; Heterogenity index_RI = RI_MAX/RI_MIN; VT, volume of distribution. Comparisons performed using Mann-Whitney U test.

Lower rank in NSVT; ^b higher rank in NSVT.
