Effects of angiotensin II (Ang II) (10−6 mol/L) and phosphoinositide 3-kinase (PI3K) inhibitor, LY 294002 (1 μmol/L), on L-type Ca+2 current (ICa,L) voltage relationship for normal cardiomyocytes, with the respective stimulation protocol shown as an inset. The inset in the graph shows the respective representative current responses at 0 mV for ICa,L. Data are presented as average current density ± SEM with n = 8.
