Diastolic current amplitude at −60 mV, maximum current amplitude during diastole, and charge carried by during diastolic depolarization for each of the 11 reconstructed current traces of Figure 6(c). (a) Diastolic current amplitude at −60 mV. (b) Maximum current amplitude during diastole. (c) Charge carried by during the 25-mV, 200-ms diastolic depolarization from the maximum diastolic potential of −63 mV to −38 mV.
