Effect of hypoxia on myocardial relaxation in isometric cat papillary muscle.


Myocardial relaxation is an important energy-dependent process. Hypoxia, unlike ischemia, has not been shown to impair myocardial relaxation. This difference may be because (a) the traditional index to assess isometric muscle relaxation (half time to relaxation or RT((1/2))) reflects both changes in developed tension as well as relaxation and (b) the… (More)
