Increased Ca2+ sparks in VM from Akita mice are attenuated in pravastatin treated mice. A. Line scan images. B. Percent of cells with sparks, C. Frequency of sparks, D. Amplitude of sparks, E. Full duration at half maximum amplitude (FDHM) and F. Full width at half maximum amplitude (FWHM). *P<0.05, **P<0.01 vs WT; †P<0.05, ††P<0.01 vs Akita. Vertical bar: 500 milliseconds, Horizontal bar: 20 μm.
