action potential duration restitution的用法和样例：
- At the single-cell level, upregulation of the L-type Ca2+ current ICa,L steepened restitution curves of action potential duration and conduction velocity compared with the control.
- The DAR and the dispersion of local activation time (AT diff) and that of the action potential duration (APD diff) were measured and calculated.
- Results Cardiomyoctes in rabbit RVOT showed marked dispersion in action potential (AP) repolarization and action potential duration(APD).
- Based on the adjusted model the effects of different defibrillation waveforms on cell action potential duration (APD) were studied.
