Mechanisms Underlying the Increase in Force and Ca2+ Transient That Follow Stretch of Cardiac Muscle: A Possible Explanation of the Anrep Effect

BV Alvarez, NG Pérez, IL Ennis… - Circulation …, 1999 - Am Heart Assoc
Myocardial stretch produces an increase in developed force (DF) that occurs in two phases:
the first (rapidly occurring) is generally attributed to an increase in myofilament calcium …
