Kurzmitteilungen und Methodisches

Summary

Calcium fluxes in frog heart ventricles are determined both during quiescence and during periods of activity. The two main results: (a) calcium influx is much increased by activity; (b) a net release of calcium from the cells occurs immediately after activity, in parallel with, and probably related to, the decline in tension of the downward “staircase”.
