More and closely distributed SCR events in cryoinjured ENDO slices. (A) Left: Map of SCR foci in control and cryoinjured ENDO LMS after pro-arrhythmic pacing. Green dots represent single SCR foci and cryoinjury is indicated with white dotted line. Right: Mean values of the number of SCR foci in LMS from the ENDO (ncontrol = 11 from 11 rats; ncryoinjury = 14 from 12 rats; comparison with Student’s t test) and from the EPI (ncontrol = 10 from 9 rats; ncryoinjury = 9 from 8 rats; comparison with Student’s t test. (B) Distribution plots of the first latencies in LMS from the ENDO (ncontrol = 11 from 11 rats; ncryoinjury = 14 from 12 rats) and from the EPI (ncontrol = 10 from 9 rats; ncryoinjury = 9 from 8 rats; comparison of GeoMean and GeoSD in ENDO and EPI after lognormal curve fitting). (C) Distribution plots of distance to the nearest SCR foci in LMS from the ENDO (ncontrol = 11 from 11 rats; ncryoinjury = 14 from 12 rats) and from the EPI (ncontrol = 10 from 9 rats; ncryoinjury = 9 from 8 rats; comparison of GeoMean and GeoSD in ENDO and EPI after lognormal curve fitting).
