Enhanced: Quenching the Spark in the Heart

David T. Yue

At each heart beat, the cells in the heart contract in response to electrical excitation. This process is mediated by a multistep pathway that results in an increase in calcium concentration. In his Perspective, Yue discusses a report in this week's issue by Gómez et al. (p. 800) that identifies the coupling step in this pathway that is defective in heart failure.
