Fig. 2. The nuclear CaT amplitude varies between atrial myocytes. (A) Pairs of cytoplasmic (black) and nuclear (red) CaTs from three different atrial myocytes. For better comparison, CaTs were normalised to the cytoplasmic CaT. (B) Histogram showing the distribution of the ratio of nuclear to cytoplasmic systolic [Ca2+] obtained under control conditions from a total of 95 atrial myocytes studied.
