Among other characteristics, the steady-state current-voltage relationship of patch-clamped single atrial myocytes from guinea-pig hearts is defined by an outward current hump in the potential region -15 to +40mV. This hump was reversibly suppressed by Co 2 + (3 mM) or nitrendipine (5 gM) and enhanc

Ca2+ release from the sarcoplasmic reticulum (SR) of mammalian cardiac myocytes occurring either due to activation by a depolarization or the resulting transmembrane Ca2+ current (ICa), or spontaneously due to Ca2+ overload has been shown to cause inward current(s) at negative membrane potentials. I
