| Description | 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. |
