Fig. 2.

Left panel, end-diastolic frames from four-chamber (A), short-axis (C) and three-chamber (E) steady state free precession (SSFP) CINE images. Despite regional artefacts, caused by either the impulse generator or the pacing leads, the image quality allows for accurate assessment of LV and RV volumes and function. LA left atrium, LV left ventricle, RA right atrium, RV right ventricle, Ao aorta. Right panel, three examples (B, D and F) of the T2-weighted, bright blood images used to localize the RV pacing lead (white arrows). The asterisks indicate the MRI markers that represent the location of the BSP electrodes
