Dynamic I-V curves from isolated cells.
A) Transmembrane potential (Vm) recorded during the action potential upstroke from six isolated rabbit cells from [43]. B) Current-voltage (I-V) relationship plotted as INa (models: lines) or (experiments: ●) versus Vm. C) Predicted Vm signals from models (lines) and average from experiments (●) during the upstroke.
