Arrhythmias & electrophysiology
Effect of posture on position of subcutaneous implantable cardioverter-defibrillator
Authors' conclusion
A supine or arms-down position during chest radiography can result in lower PRAETORIAN scores and underestimation of associated risk on defibrillation testing failure.
Study context
- Population
- Patients with a subcutaneous ICD
- Participants
- 30 patients
- Exposure
- Lateral chest radiograph standing with arms down or supine vs standard standing with arms elevated
- Outcome
- Agreement in PRAETORIAN score (weighted κ) vs standard position
Main finding
As reported in the abstract
Agreement in PRAETORIAN score vs standard position
| Group | Value | PRAETORIAN score decreased | Changed to lower risk category | High to low risk | PRAETORIAN score ≥90 |
|---|---|---|---|---|---|
| Arms down | κ 0.677 | 10 patients (33%) | 4 | ||
| Supine | κ 0.399 | 16 patients (53%) | 7 | 1 | |
| Standard position | 8 events | 8 of 30 |
