It was shown that EBP could prolong APD_(20) and APD_(90) (at 20% and 90% of repolarization in action potential duration)markedly, while over shoot(OS), resting potential(RP), amplitude of the action Potential(APA)and V_(max) were not affected.

• 结果表明EBP能明显延长APD_(20)和APD_(90)。 但对动作电位幅度(APA)静息电位(RP),超射(OS)和零期最大上升速率(V_(max))无显著影响。
