Effect of angiotensin II on the AP configuration and contractile force. (a) Superimposed tracings of a delayed after-depolarization (arrow) during a 1 Hz electrical stimulation induced by 10 nM angiotensin II. (b and c) Superimposed tracings and time course show the effects of angiotensin II (1, 10, and 100 nM) on the AP duration and contractile force. (d) The concentration–response curve for angiotensin II's effect on the 90% of the AP duration (APD90) and contractile force (n=7). *P<0.05 versus before drugs.
