The sXYYYZ.tsr.zip files, where X is the number of ECG leads, YYY is the patient number, and Z is the record number of this patient, contain following files: sXYYYZ_fin.dmy - Fine diagnostic and morphology time series sXYYYZ_raw.dmy - Raw diagnostic and morphology time series sXYYYZ_1.sta - ST segment markers according to annotation protocol A These three files are needed internally by SEMIA viewing tool. To unzip each sXYYYZ.tsr.zip file type: unzip sXYYYZ.tsr.zip --- The sXYYYZ.stf files, where X is the number of ECG leads, YYY is the patient number, and Z is the record number of this patient, are ASCII files and contain: - Raw ST level function - Raw inearly approximated baseline ST level function (raw ST reference function) - Raw ST deviation function for each ECG lead. These files are intended to users. Columns in the sXYYYZ.stf file represent: Column 1: Sample index Column 2: ST level (lead 0) (20 units = 100 uV) Column 3: ST reference (lead 0) (20 units = 100 uV) Column 4: ST deviation (lead 0) (20 units = 100 uV) Column 5: ST level (lead 1) (20 units = 100 uV) Column 6: ST reference (lead 1) (20 units = 100 uV) Column 7: ST deviation (lead 1) (20 units = 100 uV) [ Column 8: ST level (lead 2) (20 units = 100 uV) ] [ Column 9: ST reference (lead 2) (20 units = 100 uV) ] [ Column 10: ST deviation (lead 2) (20 units = 100 uV) ] --- The sXYYYZ.klt.zip files, where X is the number of ECG leads, YYY is the patient number, and Z is the record number of this patient, are compressed ASCII files and contain: - Time series of ST segment Karhunen-Loeve transform coefficients (ST segment principal components) - Time series of QRS complex Karhunen-Loeve transform coefficients (QRS complex principal components) These files are intended to users. To unzip each sXYYYZ.klt.zip file type: unzip sXYYYZ.klt.zip Columns in the sXYYYZ.klt file represent: Column 1: Sample index Column 2: ST segment KL coefficient 1 (100 units = 1 st.d.) Column 3: ST segment KL coefficient 2 (100 units = 1 st.d.) Column 4: ST segment KL coefficient 3 (100 units = 1 st.d.) Column 5: ST segment KL coefficient 4 (100 units = 1 st.d.) Column 6: ST segment KL coefficient 5 (100 units = 1 st.d.) Column 7: ST segment KL Mahalanobis distance using the first 5 KL coefficients (100 units = 1 st.d.) Column 8: QRS complex KL coefficient 1 (100 units = 1 st.d.) Column 9: QRS complex KL coefficient 2 (100 units = 1 st.d.) Column 10: QRS complex KL coefficient 3 (100 units = 1 st.d.) Column 11: QRS complex KL coefficient 4 (100 units = 1 st.d.) Column 12: QRS complex KL coefficient 5 (100 units = 1 st.d.) Column 13: QRS complex KL Mahalanobis distance using the first 5 KL coefficients (100 units = 1 st.d.)
