Effects of TTX (1 µM) on cardiomyocyte contraction function and intracellular calcium transient in the presence of Bay K 8644 (300 nM). (a) and (b) Representative recordings of myocardial sarcomere length (a) and intracellular calcium transients (b) under different conditions. (c) The myocardial contraction amplitude (n = 25), and calcium transient amplitude (n = 16) in control, Bay K 8644, and Bay K 8644 plus TTX. (d) The intracellular calcium concentration ([Ca2+]i) in myocardial cells in control, Bay K 8644, and Bay K 8644 plus TTX, n = 16. * P < 0.05 vs. control; # P < 0.05 vs. Bay K 8644.
