We carried out a series of experiment demonstrating the role of mitochondria in the cytosolic and mitochondrial Ca2+ transients and compared the results with those from computer simulation. In rat ventricular myocytes, increasing the rate of stimulation (1∼3 Hz) made both the diastolic and systolic [Ca2+] bigger in mitochondria as well as in cytosol. As L-type Ca2+ channel has key influence on the amplitude of Ca2+-induced Ca2+ release, the relation between stimulus frequency and the...
