No immediate change to ECG thresholds or anemia care; leaves open human translation of anemia-related repolarization changes.
Scheller et al. (2010) studied Normovolemic anemia. Normovolemic anemia via blood replacement with colloids vs. Baseline/higher hemoglobin levels was evaluated on Electrocardiographic changes (length of PQ, QT, QTc, ST interval, and amplitude of Q and T wave). Normovolemic anemia in a pig model caused gradual prolongation of the QT and QTc intervals, reduced T wave amplitude, and diminished QRS complex amplitude.
