Figure 1

Schematic plots of excitation-coupling and alternans in ventricular myocytes.

(A) Schematic diagram of excitation-contraction coupling in a ventricular myocyte. See text for details. (B) Voltage (V), whole-cell cytosolic Ca2+ concentration ([Ca2+]i), and whole-cell SR Ca2+ concentration ([Ca2+]SR) illustrating alternans under periodic pacing. Lk, rk+1, and uk+1 were defined graphically.
