Summary of results obtained from data analyses of optical coherence tomography images of the OFT of HH18 embryos acquired simultaneously with ECG data

Variables	NL	OTB	CON
T, ms	401 ± 34	404 ± 14	397 ± 21
ΦMI, ms	166 ± 15	188 ± 17	162 ± 12
ΦMO, ms	226 ± 18	212 ± 19	220 ± 14
PTTMI-MO, ms	60 ± 10	28 ± 11	58 ± 11

Values are means ± SD. Data are shown for the following three groups of embryos considered: 1) NL, 2) OTB, and 3) CON. Φ, time lag for maximal OFT wall contraction after cardiac depolarization marked by the R peak of the ECG signal; MI, inlet OFT myocardial wall; MO, outlet OFT myocardial wall; PTT_MI-MO, pulse transit time between the OFT inlet and outlet myocardial wall motion.
