The normal action potential of mammalian cardiac muscle has a plateau of several hundred milliseconds. It is demonstrated in these experiments that early in the relative refractory period a short action potential without a plateau may be produced. These spikes, lasting 30–50 msec, shift abruptly to action potentials of normal length as the stimulus is applied later in the relative refractory period. The possible mechanisms of this phenomenon are discussed in relation to the role of potassium… CONTINUE READING
