9	EG	EGTESTCD	ECG Test or Examination Short Name	Char	C71153 C120523	Topic	Req	Short name of the measurement, test, or examination described in EGTEST. It can be used as a column name when converting a dataset from a vertical to a horizontal format. The value in EGTESTCD cannot be longer than 8 characters, nor can it start with a number (e.g., "1TEST" is not valid). EGTESTCD cannot contain characters other than letters, numbers, or underscores. Examples : "PRAG", "QRSAG". Test codes are in two separate codelists, one for tests based on regular 10-second ECGs (EGTESTCD) and one for tests based on Holter monitoring (HETESTCD).

15	EG	EGORRES	Result or Finding in Original Units	Char		Result Qualifier	Exp	Result of the ECG measurement or finding as originally received or collected. Examples of expected values are "62" or "0.151" when the result is an interval or measurement, or "ATRIAL FIBRILLATION" or "QT PROLONGATION" when the result is a finding.
16	EG	EGORRESU	Original Units	Char	C71620	Variable Qualifier	Perm	Original units in which the data were collected. The unit for EGORRES. Examples: "sec" or "msec".
17	EG	EGSTRESC	Character Result/Finding in Std Format	Char	C120522 C71150	Result Qualifier	Exp	Contains the result value for all findings, copied or derived from EGORRES in a standard format or standard units. EGSTRESC should store all results or findings in character format; if results are numeric, they should also be stored in numeric format in EGSTRESN. For example, if a test has results of "NONE", "NEG", and "NEGATIVE" in EGORRES and these results effectively have the same meaning, they could be represented in standard format in EGSTRESC as "NEGATIVE". For other examples, see general assumptions. Additional examples of result data: "SINUS BRADYCARDIA", "ATRIAL FLUTTER", "ATRIAL FIBRILLATION". Test results are in two separate codelists, one for tests based on regular 10-second ECGs (EGSTRESC) and one for tests based on Holter monitoring (HESTRESC).

27	EG	EGBLFL	Baseline Flag	Char	C66742	Record Qualifier	Perm	Indicator used to identify a baseline value. Should be "Y" or null. Note that EGBLFL is retained for backward compatibility. The authoritative baseline for statistical analysis is in an ADaM dataset.
28	EG	EGDRVFL	Derived Flag	Char	C66742	Record Qualifier	Perm	Used to indicate a derived record. The value should be "Y" or null. Records that represent the average of other records, or that do not come from the CRF, or are not as originally collected or received are examples of records that would be derived for the submission datasets.

40	EG	EGTPTNUM	Planned Time Point Number	Num		Timing	Perm	Numerical version of EGTPT to aid in sorting.
41	EG	EGELTM	Planned Elapsed Time from Time Point Ref	Char	ISO 8601	Timing	Perm	Planned elapsed time (in ISO 8601) relative to a fixed time point reference (EGTPTREF).
