VSD's undergo changes in their fluorescence spectra, in response to changes in the surrounding electric field. This optical response is sufficientlyfast to detect transient potential changes in excitable cardiac cells. However, our previous Langendorf perfused heart studies have suggested changes in ECG signals in time and time-frequency domain caused by application of VSD during optical mapping. D Detailed analysis of changes is needed to reveal impact to particular fractions of a heart cycle. Rabbit hearts are employed in our laboratory to record monophasic action potentials using VSDs in isolated hearts perfused according to Langendorf. The spontaneously beating heart is mounted on Langendorf set and perfused with constant perfusion pressure with Krebs-Henseleit solution (37\u00B0C, 1,25mM Ca2+). After control period (20 min), the heart is loaded with di-4-ANEPPS (2uM) diluted in perfusion soluti"@en . "ECG signal, optical mapping, dynamic time warping"@en .
