Fig. 1

a The macroscopic view of a murine supraventricular region and system of the pulmonary veins. LL, RML, RIL, RSL, AL: left, right middle, inferior, superior accessory lung lobes; RAA, LAA: right and left atrial appendages, RA: left atria, PT: pulmonary tract, Ao:aorta, R-PV, R-A-PV, L-PV: right, ascending and left pulmonary veins. PV mouth (PV-m): LA-PV junction region. Scale bar 5 mm. b Representative example of the murine PV activation map. The activation is initiated by the electrical pacing applied to atrial part of the preparation. The arrows in the activation map indicate direction of the excitation, the length of the arrows corresponds with conduction velocity. c Representative examples of the “optical” action potentials in PV mouth (1) and distal region of the PV (2)
