| Description | The paper deals with the time-frequency analysis of ECG signals using the wavelet transform (WT). Reasons for WT implementation are justified. The electrical activity of 11 rabbit isolated hearts was recorded before and during myocardial acute ischemia. The recorded data were analysed using WT. The results show that under experimental condition myocardial ischemia can be reliably detected within one minute after coronary artery occlusion. |
