Measurements of intracellular Ca²⁺ transients in neonatal cardiomyocytes. The cells were exposed to LPS for 8 or 16 h. a A demonstration of Ca²⁺ transient of multiple cells (left) and a representative view of cultured rat neonatal cardiomyocytes under ×40 magnification (right). b Amplitude of Ca²⁺ transient (F_peak – F₀/F₀ – B). c Time to 50% Ca²⁺ decay (TR₅₀). d Time constant of Ca²⁺ decay (Tau). n = 130–150. * p < 0.05 compared to the control.
