Local regulation of the threshold for calcium sparks in rat ventricular myocytes: role of sodium-calcium exchange
1. To determine whether Na(+)-Ca(2+) exchange modulates Ca(2+) sparks, we studied enzymatically isolated patch clamped rat ventricular myocytes loaded with the Ca(2+)-sensitive indicator fluo-3, using confocal microscopy at 20–22 °C. Two-dimensional images of Ca(2+) sparks were recorded at 240 Hz us...
