Mechanism of Discordant Alternans in Spatially Homogeneous Tissue
Mari A. Watanabe, Flavio H Fenton, Steven J. Evans +2
Discordant alternans,the phenomenon of 2 separate cardiac tissue locations exhibiting action potential duration (APD) alternans of opposite phase, appears to be a potential mechani…
