Table 2 Performance indices of myocardial ischemia detection (the 10th minute of ischemia) using lead I AUCQRS calculated for hearts with low (L) and high (H) LV mass fraction and united group (L&H)

From: Effect of increased left ventricle mass on ischemia assessment in electrocardiographic signals: rabbit isolated heart study

Analysed group Se, % Sp, % Cut-off, mV·ms Group used for cut-off calculation
L 89 94 −8* L
H 100 100 39* H
L&H 94 90 −8* L&H
L 79 98 39 H
H 100 85 −8 L
L&H 89 99 39 H
  1. Se – sensitivity; Sp – specificity; * – optimal (‘adjusted’) discriminating cut-off derived from ROC curve for corresponding group
