Description	The optical mapping of action potentials from heart surface has been used extensively as a new possibility of non-invasive recording methods. It employs application of voltage-sensitive dyes(VSDs). Previously, VSDs have been successfully used in myocardial ischemia studies. Our previous Langendorff-perfused heart experiments have suggested shape changes in ECG signals in time and time-frequency domain caused by application of VSD di-4-ANEPPS during optical mapping. These changes went through detailed analysis to reveal impact on particular fractions of a heart cycle. The heart cycle was divided into three parts, corresponding to P-Q segments, QRS complexes, and ST-T segments. Dynamic time warping (DTW) is applied to all marked segments in each experimental period (control, loading, and washout phase).
