Pretty much what the text says. For the sake of simplicity let's imagine we have this scenario here:


Now my question is. Say we took the same myocardial fiber in a resting(polarized) state and gave it a STIMULUS but at a location past the HALF-WAY point and at the same time let's just imagine there was a BLOCK at the same level of the stimulus so that the depolarization wave couldn't go back towards the Negative electrode only towards the Positive electrode. Would it still give a positive deflection??

    Is your question answered if I remind you that measured electrical potentials (voltages) are always relative to something? That is, voltage is a difference in electrical potential between Point A and Point B?

  • I believe from what I understood It would be a a POSITIVE DEFLECTION but with a smaller amplitude. Is that correct?
