  • To study the effects of changes in sarcoplasmic reticulum (SR) intraluminal Ca2+ on the Ca2+ release mechanism, we correlated the activity of single cardiac ryanodine receptor (RyR) channels, monitored in planar bilayers, with the properties of spontaneous elementary Ca2+ release events (sparks) in intact ventricular myocytes, monitored by scanning confocal microfluorimetry. Under both normal conditions and Ca2+ overload, induced by elevation of extracellular [Ca2+], Ca2+ sparks represented… CONTINUE READING
