in the heart's pacemaker cells, the timing of the heart rate is determined by the diffusion of calcium into the cells through slow calcium channels. Temperature can alter this timing because it... can affect the rate of facilitated diffusion of calcium. can block ACh receptors. can accentuate sympathetic receptor action.
