Figure 7.

Global temperature dependency of Ca2+ transients ΔF/F.(A) Temperature dependency of Ca2+ transients expressed as ΔF/F. An epicardial Ca2+ transient recorded at different temperatures in hearts paced at 4 Hz. It is possible to observe that as we increase the temperature, the ΔF/F decreases. (B) Amplitude of the peak ΔF/F values as a function of temperature. Interestingly, the values of the ΔF/F are smaller than in isolated myocytes due to the fluorescent contribution of endothelial and smooth muscle cells. (C) Temperature dependency of the diastolic fluorescence as a function of temperature. (D) Temperature dependency of the systolic fluorescence as a function of the temperature (n = 4 hearts).
