Fig. 3From: Clinical characteristics and therapeutic strategy of frequent accelerated idioventricular rhythmROC curve of AIVR burden for predicting impaired LVEF. The AUC was 0.971. AIVR burden was negatively correlated with LVEF (P < 0.001). An AIVR burden of over 73.8%/day was predictive of impaired LVEF (< 50%), with a sensitivity of 100% and a specificity of 94.1%.
