Effects of Short-Term Arm Sling Use After Cardiac Implantable Electronic Device Placement (CIED-SLING24)

Cardiac implantable electronic devices (CIEDs), including permanent pacemakers, implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy (CRT) devices, are widely used in the management of bradyarrhythmias, tachyarrhythmias, and heart failure. The early postoperative period following CIED implantation is important because device-related complications such as pocket hematoma, bleeding, swelling, wound-related problems, and lead-related complications may occur during this period.

Postoperative restriction of arm movement and the use of an arm sling are commonly applied in clinical practice; however, practices vary considerably between centers, and there is no clear consensus regarding the necessity or optimal duration of arm sling use following CIED implantation. While arm immobilization may provide a sense of protection and may potentially reduce movement-related concerns, unnecessary restriction may also negatively affect comfort, pain, mobility, and the overall patient experience.

Previous studies have mainly focused on device-related complications or shoulder function following CIED implantation. Evidence regarding the effects of short-term medical arm sling use on patient-centered outcomes, particularly comfort, pain, and satisfaction, together with early device-related complications, remains limited. Therefore, this study is designed to provide randomized controlled evidence on the clinical and patient-centered effects of using a medical arm sling during the first 24 hours after CIED implantation.
