Consecutive Fourier analysis along length (A) and width (B) directions calculated from bright field and fluorescence images of tetramethylrhodamine methyl ester (TMRM) loaded cardiomyocytes. Low concentrations of diazoxide (Dz; 30 µM) did not shift the sarcomere peak (C), but shifted the frequency of the mitochondrial peak (D) along the length-axis and (E) width-axis to the left by ∼1%.
