Abstract
This paper deals with analysis of changes in ECG signals caused by application of voltage-sensitive dye (VSD), which is necessary part of touch-less recording of electrical activity of the heart by optical way. The dye is injected into perfusate during animal Langendorff experiment. The recorded ECG signals were divided into P-Q segments, QRS complexes, and ST-T segments of selected consecutive heart cycles in each experimental period. Changes of ECG cycles caused by VSD application were studied during experimental phases. The analysis were performed in time and time-frequency domain and compared.
