Concordant and Discordant Alternans & Control of Alternans

• Voltage alternans in single cells and APD Restitution
• Normal restitution (1D map, period-doubling Hopf bifurcation)
• Biphasic restitution (1D map, chaotic dynamics)
• Restitution, alternans as a function of CL (1D map with pitchfork bifurcation)
• Restitution, alternans as a function of CL (1D map with border-collision bifurcation)

• Calcium alternans
• Intracellular calcium alternans due to a steep relationship between the SR content and the calcium efflux, using the Eisner-Choi-Diaz-Neill-Trafford map

• 1D rings
• Fenton-Karma model on a 1D ring and APD oscillations as a function of ring size (spatially discordant alternans)
• 1D partial alternans suppression (electrotonic effects)
• 1D alternans suppression (electrotonic effects)

• Alternans Control
• Control of APD alternans on a ring using an external signal
• Control of APD alternans on a ring using an external signal (more control options)
