May be used to create RELREC to link this record with a record in another domain. | N/A | N/A | This can be used to confirm that the appropriate data record is present in the electronic transfer if this reference ID happens to be available to the site at the time of collection. Examples: Universally Unique Identifier (UUID) for external waveform file, session number automatically generated by electronic equipment. This can also be used to link. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 11 | EGMETHOD | Method of ECG Test | Method of the test or examination | What was the method used for the ECG? | Method | Char | O | Record the method used for the ECG. | EGMETHOD | Maps directly to the tabulation variable listed in the Tabulation Target column. | (EGMETHOD) | N/A | Results may be affected by whether conditions for ECG as specified in the protocol were properly met. If the protocol requires this type of information, then this question may be included to confirm that the method used matches the protocol. The following are examples of when it is not necessary to collect these data on the CRF:
|
| Findings | EG | Central Reading with Investigator Assessment | N/A | 12 | EGLEAD | ECG Lead Location Used for Measurement | The lead used for the measurement (e.g., "LEAD I", "LEAD II", "LEAD III", "LEAD rV2", "LEAD V1") | Which lead location was used for this measurement? | Lead Location | Char | O | Record which lead was used for this measurement. | EGLEAD | Maps directly to the tabulation variable listed in the Tabulation Target column. | (EGLEAD) | N/A | This is used when more specificity for the location is desired for the ECG data. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 13 | EGPOS | ECG Position of Subject | The position of the subject during the ECG measurement | What was the position of the subject during the ECG measurement? | Position | Char | O | Record the position of the subject during the ECG. | EGPOS | Maps directly to the tabulation variable listed in the Tabulation Target column. | (POSITION) | N/A | Results may be affected by whether conditions for ECG as specified in the protocol were properly met. If the protocol requires this type of information, then this question may be included to confirm that the subject's position matches the protocol. The following are examples of when it is not necessary to collect these data on the CRF:
|
| Findings | EG | Central Reading with Investigator Assessment | N/A | 14 | EGDAT | Date of ECG | The date the ECG was performed, represented in an unambiguous date format (e.g., DD-MON-YYYY) | What was the date of the ECG? | ECG Date | Char | R/C | Record the date ECG was done using this format (DD-MON-YYYY). | EGDTC | This does not map directly to a tabulation variable. For the tabulation dataset, concatenate all collected DATE and TIME components and populate the tabulation variable EGDTC in ISO 8601 format. | N/A | N/A | A complete date is expected. The date of collection may be determined from the date of visit (VISDAT) and if so, a separate assessment date field is not required. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 15 | EGTPT | ECG Planned Time Point Name | A text description of planned time point when measurements should be taken as defined in the protocol | What was the planned time point of the ECG measurement? | [Planned Time Point Name] | Char | R/C | Record the time point labels for when the ECG test should be taken, if not on the CRF. | EGTPT | Maps directly to the tabulation variable listed in the Tabulation Target column. Tabulation time point anchors EGTPTREF (text description) and EGRFTDTC (date/time) may be needed, as well as tabulation variables EGTPTNUM, EGELTM. | N/A | N/A | Planned time points are needed to differentiate multiple sequential assessments. It is recommended that time points should be on the CRF rather than collected in a free-text field. If the form is laid out as a grid, then words such as "Planned Time Point" can be included as the column heading. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 16 | EGTIM | Time of ECG | Time of ECG, represented in an unambiguous time format (e.g., hh:mm:ss) | What was the time the ECG was collected? | ECG Time | Char | R/C | Record the time the ECG was done (as complete as possible). | EGDTC | This does not map directly to a tabulation variable. For the tabulation dataset, concatenate all collected DATE and TIME components and populate the tabulation variable EGDTC in ISO 8601 format. | N/A | N/A | May be required when multiple assessments are done on 1 day or when the timing in relationship to study product is required for analysis. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 17 | EGEVAL | ECG Evaluator | The role of the person who provided the evaluation | Who provided the information?; Who was the evaluator? | [Evaluator/Reporter] | Char | O | Select the role of the person who provided the evaluation (e.g., INVESTIGATOR, ADJUDICATION COMMITTEE, VENDOR). | EGEVAL | Maps directly to the tabulation variable listed in the Tabulation Target column. | (EVAL) | N/A | Used only for results that are subjective (e.g., assigned by a person or a group). May be pre-printed or collected. Applicants may collect the data using a subset list of controlled terminology on the CRF. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 18 | INTP_EGORRES | ECG Interpretation | Overall interpretation of the result of the measurement or finding | What was the interpretation of the ECG? | Interpretation | Char | O | Record overall interpretations of the ECG. | EGORRES | This does not map directly to a tabulation variable. For the tabulation dataset, the recorded interpretation is populated into the tabulation variable EGORRES where EGTEST= "Interpretation", and EGTESTCD="INTP". | N/A | N/A | The overall interpretation of an ECG is mapped into the appropriate tabaulation test and result variables. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 19 | EGCLSIG | ECG Clinical Significance | An indication of whether the ECG results were clinically significant | Was the ECG clinically significant? | Clinically Significant | Char | HR | Record whether ECG results were clinically significant. | SUPPEG.QVAL | This does not map directly to a tabulation variable. This information could be represented in a SUPPEG dataset as the value of SUPPEG.QVAL where SUPPEG.QNAM = "EGCLSIG" and SUPPEG.QLABEL="Clinically Significant". | (NY) | N/A | Could apply to specific measurements or to overall interpretation. In this scenario, clinical significance could be provided by the investigator. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 20 | EGMHNO | Related Medical History Event ID | Identifier for the medical history event that was reported as a clinically significant ECG finding | What was the identifier for the medical history event that was reported as a clinically significant ECG finding? | Medical History Event Identifier | Char | O | Record the identifier for the medical history event that was reported as a clinically significant ECG finding. | N/A | This does not map directly to a tabulation variable. For the tabulation datasets, may be used to create RELREC to link this record with a record in the MH domain. | N/A | N/A | Intent is to establish a link between the clinically significant ECG finding and the medical history event that was reported. EGMHNO can be used in RELREC to identify a relationship between records in EG dataset and records in the MH dataset. |
| Findings | EG | Central Reading with Investigator Assessment | N/A | 21 | EGAENO | Related Adverse Event ID | Identifier for the adverse event that was reported as a clinically significant ECG finding | What was the identifier for the adverse event(s) that was reported as a clinically significant ECG finding? | Adverse Event Identifier | Char | O | Record the identifier for the adverse event that was the reported as a clinically significant ECG finding. | N/A | This does not map directly to a tabulation variable. For the tabulation datasets, may be used to create RELREC to link this record with a record in the AE domain. | N/A | N/A | Intent is to establish a link between the clinically significant ECG finding and the AE that was reported. EGAENO can be used to identify a relationship between records in EG dataset and records in the AE dataset. |
