Comparing human ventricular electrical restitution curves based on the action potential duration. Human APD90 restitution curves were separated into short APD (APD90 < 250 ms) and long APD (APD90 > 300 ms) groups. The data points up to 1000 ms diastolic interval were fitted by single exponential function. The inset shows the kinetical time constants for the two groups.
