阈电位

这种钾通道在低于阈电位时开始被激活，产生IA抵消了刺激电流，去极化几乎被抑制，延长膜电位去极化。

This potassium channel below the threshold potential is activated when you start to produce export-oriented IA stimulus offset current , the depolarization was almost inhibited , extended membrane potential depolarization .

用两倍阈电位的脉冲刺激右室心肌，并以5～10V递增，检测VFT。

Right ventricular stimuli were introduced at twice diastolic threshold and subsequently increased in 5 ~ 10 V intervals to measure VFT .

M通道是神经系统广泛分布的一种电压依赖性钾离子通道，该通道在神经元阈电位附近激活，产生M电流。

M channel , a voltage-dependent potassium channel , has been found in a variety of neurons . It is activated near the threshold of neuron action potential , producing a primary K ~ + current , namely the M-current .
