The sXYYYZ_SS-EE.png files contain figures of trend plots of diagnostic and morphology parameters of the records and their annotation streams. X is the number of ECG leads, YYY is the patient number, Z is the record number of this patient, SS is the start time of the trends in hours, and EE is the end time of the trends in hours. Each file contains a figure with following plots (from top to bottom): Heart Rate: Heart rate in bpm --- Combined Epis.: Combined (in the sense of logical OR) ST segment change episode annotation stream obtained by merging together the ST episode annotations of ischemic ST episodes and of heart-rate related ST episodes from the simultaneous leads into one single ST annotation stream (narrow rectangles: ischemic ST episodes, wide rectangles: heart-rate related ST episodes) --- ST Level: ST level function measured at the J + 80(60) milliseconds (depending oh heart rate) in uV (lead 0) ST Reference (red): ST reference function in uV (lead 0) ST Deviation: ST deviation function in uV (lead 0) Is/RR: ST segment episode annotation stream (lead 0) (narrow rectangles: ischemic ST episodes, wide rectangles: heart-rate related ST episodes) Ax/CC: ST segment shifts (lead 0) (short vertical lines: axis shifts, longer vertical lines: QRS conduction changes) ST Slope: Amplitude difference in uV between the ST level function and the ST level function measured at the J + 20 milliseconds point (lead 0) --- ST Level: ST level function measured at the J + 80(60) milliseconds (depending oh heart rate) in uV (lead 1) ST Reference (red): ST reference function in uV (lead 1) ST Deviation: ST deviation function in uV (lead 1) Is/RR: ST segment episode annotation stream (lead 1) (narrow rectangles: ischemic ST episodes, wide rectangles: heart-rate related ST episodes) Ax/CC: ST segment shifts (lead 1) (short vertical lines: axis shifts, longer vertical lines: QRS conduction changes) ST Slope: Amplitude difference in uV between the ST level function and the ST level function measured at the J + 20 milliseconds point (lead 1) --- [ ST Level: ST level function measured at the J + 80(60) milliseconds (depending oh heart rate) in uV (lead 2) ] [ ST Reference (red): ST reference function in uV (lead 2) ] [ ST Deviation: ST deviation function in uV (lead 2) ] [ Is/RR: ST segment episode annotation stream (lead 2) (narrow rectangles: ischemic ST episodes, wide rectangles: heart-rate related ST episodes) ] [ Ax/CC: ST segment shifts (lead 2) (short vertical lines: axis shifts, longer vertical lines: QRS conduction changes) ] [ ST Slope: Amplitude difference in uV between the ST level function and the ST level function measured at the J + 20 milliseconds point (lead 2) ] --- Unread/Noise l0: Unreadable intervals and noisy events (lead 0) Unread/Noise l1: Unreadable intervals and noisy events (lead 1) [ Unread/Noise l2: Unreadable intervals and noisy events (lead 2) ] Abnormal Beats: Abnormal heart beats --- QRS KL1-5: Time series of the first 5 Karhunen-Loeve coefficient representation of QRS complexes (units in st.d.) QRS Distance: Mahalanobis distance measure when using the first 5 Karhunen-Loeve coefficients of QRS complexes (units in st.d.)
