Cardiomyocytes (Ventricular Myocytes) - Recordings

   Port-a-Patch data and applicatons:
Thanks to S. Rakovic and D. Terrar from University of Oxford, for preparing the cardiomyocytes used in these experiments.

Ca²⁺ current recorded from a ventricular myocyte. Raw current voltage relationship and peak current data are plotted (top). From the IV-plot the half-activating voltage was determined as -16 mV. The current was later blocked by the L-type Ca²⁺ channel blocker, nifedepine (10 µM). Currents were elicited by stepping to +10 mV for 200 ms from a holding potential of -40 mV every 5 seconds.
