Figure 5: Resting and peak calcium concentrations in cardiomyocytes and time from peak to 75% decay (TD75) under different frequencies of stimulations with and without ISO treatment. Data are mean ± SEM, = at least 30 myocytes from six hearts for each concentration in each group. At least 5 myocytes were from each heart. * or **   versus baseline.
