This is the first session of the Basic/Translational Science Symposium, focused on "The Importance Of Cellular Diversity And Intercellular Communication For Heart Rhythm". It will cover the diversity of non-myocytes in the heart and the influence of various cell populations on cardiac electrophysiology.

• Recognize the diversity of cell populations in the heart.
• Explain the mechanisms of heterocellular interactions in the heart.
• Appreciate the influence of heterocellular interactions on the heart's electrical activity.
