Using the single electrode voltage-clamp technique, vascular smooth muscle cells from the guinea pig portal vein showed an initial inward (Ca2+) current followed by an outward current which peaked within 100 ms and then declined to a steady level in a few seconds. Caffeine (1 mmol/l) selectively blo

Transient inward currents (Iti) during oscillations of intracellular [Ca2+] ([Ca2+]i) in ventricular myocytes have been ascribed to Na/Ca exchange. We have investigated whether other Ca2+-dependent membrane currents contribute to Iti in single guinea-pig ventricular myocytes, by examining membrane c
With the action potential clamp procedure we studied the contribution of various ionic currents to the action potential in single ventricular myocytes. Action potentials were elicited by a current pulse through the suction pipette and recorded by a computer. A representative action potential was the
