Row 1:	Shows a measurement of ventricular rate. This result was assessed as not clinically significant (EGCLSIG = "N").
Row 2:	Shows a measurement of PR interval. This result was assessed as clinically significant (EGCLSIG = "Y").
Rows 3-4:	These interval measurements were collected in seconds. However, in this submission, the standard unit for these tests was milliseconds, so the results have been converted in EGSTRESC and EGSTRESN.
Row 5:	Show Shows "QTcB Interval, Aggregate". This result was derived by the sponsorapplicant, as indicated by the “Y” in the EGDRVFL column. Note that EGORRES is null for these derived records.
Row 6:	Shows the result the result of the TEST "Interpretation" (i.e., the interpretation of the ECG strip as a whole), which for this ECG was ECG was "ABNORMAL". This result was assessed as clinically significant (EGCLSIG = "Y").
