摘要：
Non-stationary analysis of ECG using Choi-Williams (CW) distribution is presented. Analysis was applied on subjects with AMI who have undergone thrombolysis, in VI Holder recordings. Two groups of patients were regarded: successfully and non-successfully thrombolysed patients. The time-frequency map generated by, CW transform was divided in nine areas, relevant to ECG features. Characteristic parameters were extracted from each area and linear discriminant analysis was applied on these parameters, leading to a prediction index. Applying the method to ECGs at the sixth hour after lysis, the successfully, thrombolysed patients were distinct from the non-successfully thrombolysed ones.
