in Access database | Possible values | Description |
|
| Initial rhythm | init_rhy | 1 = asystole,
2 = VF,
3 = pulseless VT,
4 = organized,
5 = indeterminate (VF/organized),
6 = indeterminate (VF/asystole),
7 = indeterminate (brady),
8 = indeterminate,
9 = unknown | Description of what the initial rhythm recorded was as determined from the AED. Codes in parenthesis refer to indeterminate between the two stated rhythms.
If initial rhythm NOT VF and patient subsequently fibrillates, record original VF onset time, for substudy of secondary VF. |
|
| Preshock rhythm | rhyb4 | 1 = asystole,
2 = vf,
3 = vt,
4 = org,
5 = indeterm-(vf/org),
6 = indeterm-(vf/asys),
7 = indeterm-brady,
8 = indeterm,
9 = unknown | Description of what the preshock rhythm recorded was. Codes in parenthesis refer to indeterminate between the two stated rhythms. |
|
| Rhythm 10 secs after the last shock | r10 | 1 = asystole,
2 = vf,
3 = vt,
4 = org,
5 = indeterm-(vf/org),
6 = indeterm-(vf/asys),
7 = indeterm-brady,
8 = indeterm,
9 = unknown | Description of what rhythm recorded 10 seconds after the shock was. Codes in parenthesis refer to indeterminate between the two stated rhythms.
Use discretion to take the rhythm ±5 seconds from 10 seconds after shock. |
|
| Rhythm 30 secs after the last shock | r30 | 1 = asystole,
2 = vf,
3 = vt,
4 = org,
5 = indeterm-(vf/org),
6 = indeterm-(vf/asys),
7 = indeterm-brady,
8 = indeterm,
9 = unknown | Description of what rhythm recorded 30 seconds after the shock was. Codes in parenthesis refer to indeterminate between the two stated rhythms.
Use discretion to take the rhythm ±5 seconds from 30 seconds after shock. |
|
| Rhythm 60 secs after the last shock | r60 | 1 = asystole,
2 = vf,
3 = vt,
4 = org,
5 = indeterm-(vf/org),
6 = indeterm-(vf/asys),
7 = indeterm-brady,
8 = indeterm,
9 = unknown | Description of what rhythm recorded 60 seconds after the shock was. Codes in parenthesis refer to indeterminate between the two stated rhythms
Use discretion to take the rhythm ±5 seconds from 60 seconds after shock. |
|
| Rhythm 120 sec after the last shock | r120 | 1 = asystole,
2 = vf,
3 = vt,
4 = org,
5 = indeterm-(vf/org),
6 = indeterm-(vf/asys),
7 = indeterm-brady,
8 = indeterm,
9 = unknown | Description of what rhythm recorded 120 seconds after the shock was. Codes in parenthesis refer to indeterminate between the two stated rhythms.
Use discretion to take the rhythm ±5 seconds from 120 seconds after shock. |
|
| VF prior to next shock? | vfpr | 1 = yes, 2 = no, and 9 = unknown | Description of whether or not there was VF between shocks, or between the last shock and the end of this recording as determined from audio or the MRIF. Not to capture VF at any time after device turned off. |
|
| Organized rhythm prior to next shock? | orgpr | 1 = yes, 2 = no, and 9 = unknown | Description of whether or not there was an organized rhythm between shocks, or between the last shock and the end of the recording.
Best organized rhythm (wide/narrow, and rate) will be taken within 3 minutes of the final shock on recording. |
|
| ROSC | rosc | 1 = yes, 2 = no, and 9 = unknown | Description of whether return of spontaneous circulation occurred. |
