Nonlinear and stochastic dynamics in the heart

Z Qu, G Hu, A Garfinkel, JN Weiss - Physics reports, 2014 - Elsevier
In a normal human life span, the heart beats about 2–3 billion times. Under diseased
conditions, a heart may lose its normal rhythm and degenerate suddenly into much faster …

Ryanodine receptor dispersion disrupts Ca2+ release in failing cardiac myocytes

TR Kolstad, J van den Brink, N MacQuaide, PK Lunde… - Elife, 2018 - elifesciences.org
