From: Model-based estimation of QT intervals of mouse fetal electrocardiogram
Bland–Altman and correlation analyses were performed to compare the Q-Ac interval values that were estimated by the two measurers a, and to compare model-based QT interval values with Q-Ac interval values of the two measurers b–c. QT and Q-Ac intervals were estimated beat by beat and the total number of heart beats was 309 from five fetal mice. a 95% of the values are within the limits of agreement (r = 0.93, P < 0.05). b 93% of the values are within the limits of agreement (r = 0.89, P < 0.05). c 92% of the values are within the limits of agreement (r = 0.91, P < 0.05)
