Synchronization of spatially discordant voltage and calcium alternans in cardiac tissue
The heart is an excitable medium which is excited by membrane potential depolarization
and propagation. Membrane potential depolarization brings in calcium (Ca) through the Ca …

The calcium transient coupled to the L-type calcium current attenuates cardiac alternans
M Warren, S Poelzing - Frontiers in Physiology, 2024 - frontiersin.org
Cardiac action potential (AP) alternans have been linked to the development of arrhythmia.
AP alternans may be driven by AP instabilities, Ca2+ transient (CaT) instabilities, or both …
