Small molecules affect cardiomyocyte contraction rates. The effect of small molecules on cardiomyocyte contraction rate was assessed by monitoring intracellular calcium fluctuations, where an increase in calcium coincides with cardiomyocyte contraction. Cardiomyocytes were loaded with the fluorescent calcium indicator, Fluo-4, prior to small molecule treatment. Individual wells were first monitored for baseline rates of calcium fluctuation represented as beats per minute (bpm). Phenylephrine (3μM, Catalog # 2838), an alpha 1-adrenoceptor agonist, increased the calcium fluctuation rate of cardiomyocytes compared to untreated cells
