    "abstract": "We investigate numerically and analytically the coupled dynamics of\ntransmembrane voltage and intracellular calcium cycling in paced cardiac cells\nusing a detailed physiological model and its reduction to a three-dimensional\ndiscrete map. The results provide a theoretical framework to interpret various\nexperimentally observed modes of instability ranging from electromechanically\nconcordant and discordant alternans to quasiperiodic oscillations of voltage\nand calcium.",
