Oxygen demand of calcium-tolerant adult cardiac myocytes.
Isolated Ca2+-tolerant myocytes are mechanically at rest. Therefore, minimal oxygen demands should be expected. If oxygen consumption is measured without mechanical agitation of the cells, consumption rates comparable to those of the arrested myocardium are measured. In the current literature, much higher values are usually reported. It is suggested that these are due to mechanical stimulation of the cells in stirred suspensions.
