Abstract
1.
1. Separated adult mammalian and avian heart muscle cells were observed to contract and relax spontaneously under conditions which cause contracture of reptilian and amphibian heart muscle cells.
2.
2. The role of catecholamines in imparting resistance to potassium-induced contracture could not be demonstrated with the separated cells, as it has with papillary muscle preparations.
