Will radio frequency interference make my heart skip a beat?
What is RF interference?
RFI, or radio frequency interference, occurs when electromagnetic energy from nearby devices disrupts the proper functioning of electronic devices that operate on similar radio frequencies. The interference can manifest in different forms, including noise, distortion, or complete disruption of communication. For a more detailed explanation, click here.
Are implantable medical devices susceptible?
Devices, such as pacemakers, implantable cardioverter- defibrillators (ICDs), neurostimulators, cochlear implants, and others, rely on precise electrical signals to regulate bodily functions or deliver therapeutic treatments. When exposed to RF interference, these signals can become distorted or interrupted, potentially leading to serious consequences for the patient.
The interaction between RF signals and implantable medical devices can vary depending on several factors, including the RF source’s frequency, amplitude, and proximity to the implanted device. Higher frequencies and closer proximity to the device generally increase the likelihood of interference.
Additionally, certain implantable devices may be more susceptible to RF interference than others, depending on their design and materials.
Consequences of RF and medical device interference.
The consequences of RF interference with implantable medical devices can range from minor disruptions to life-threatening events. In some cases, interference may cause the device to deliver inappropriate therapy or fail to deliver necessary treatment, potentially leading to arrhythmias, seizures, or other adverse events.
Patients may experience dizziness, palpitations, or device alarms signaling malfunction.
