Key result
Extending the arm above the head on the ipsilateral side of the ICD increased the distance between the LVAD and ICD, eliminating electromagnetic interference and allowing device reprogramming.
Case Report (n=1)
A simple physical maneuver of extending the ipsilateral arm above the head can relieve electromagnetic interference between an LVAD and an ICD, allowing for successful device interrogation and reprogramming.
We introduced a simple technique to eliminate electromagnetic interference between a left ventricular assist device (LVAD) and an implantable cardioverter defibrillator (ICD). A 43-year-old male with heart failure and a reduced ejection fraction who had an ICD presented with decompensated heart failure and received an LVAD as a bridge to transplant. Remote monitoring showed persistent atrial fibrillation causing an inappropriate ICD shock leading to a decision to disable shock therapies. However, an in-office interrogation was unsuccessful due to electromagnetic interference. Patient was instructed to extend his arm above his head on the ipsilateral side of the ICD, thus increasing the distance between LVAD and ICD, eliminating the interaction to allow reprogramming of the device.

Jin et al. (2020) conducted a case report in Heart failure with reduced ejection fraction, LVAD, ICD, electromagnetic interference (n=1). Extending arm above head on the ipsilateral side of the ICD was evaluated on Elimination of electromagnetic interference to allow reprogramming of the device. Extending the arm above the head on the ipsilateral side of the ICD increased the distance between the LVAD and ICD, eliminating electromagnetic interference and allowing device reprogramming.
