Hi, in my book it says that calcium does not affect conductor cells, yet the increase of calcium permeability results in a positive Dromotropic effect. Is there any logical explanation to this?

not that it really matters, but i think you'll find most medical terms come from greek rather than latin. chronotropy, for example.
