| Description | The paper presents methods for analysis of changes in ECG signals caused by application of voltage-sensitive dye (VSD). The signals were experimentally recorded from isolated guinea pig hearts prior optical recording. The analysis was performed in time and time-frequency space with focus on changes occurring in QRS complex. The influence of VSD was examined in a 70-second interval after VSD application in detail and then periodically for the following ten minutes. The results were compared to those from traditional R-R interval analysis. |
