A non-invasive 3-electrode lead II method provides an accurate, reproducible, and rapid alternative to radiotelemetry for measuring ECG parameters in anesthetized mice.
Kim et al. (2015) studied Healthy mice (ECG validation) (n=24). Non-invasive ECG measurement (lead II) vs. Balb/c vs FVB strains was evaluated on Heart rate (BPM) (p=5.67E-06). A non-invasive ECG measurement method using three electrodes for lead II in mice provided stable and reproducible recordings, successfully detecting significant differences in heart rate between Balb/c and FVB strains.
