Do cell phones interfere with pacemakers?

As a biomedical engineer with a focus on medical devices, I can provide some insights into the interaction between cell phones and pacemakers. Cell phones operate using radiofrequency (RF) energy to transmit voice and data signals. Pacemakers, on the other hand, are medical devices that use electrical impulses to regulate the heartbeat. Historically, there were concerns about cell phones potentially interfering with the proper functioning of pacemakers due to the electromagnetic interference (EMI) they might cause. However, modern pacemakers are designed to be resistant to such interference. The American Heart Association (AHA) has stated that there is no evidence to suggest that cell phones cause harm to people with pacemakers. Most pacemakers are now shielded and have filters that protect them from EMI. Additionally, the Federal Communications Commission (FCC) has guidelines in place that limit the RF emissions from cell phones, which further reduces the risk of interference. However, as a precaution, it is generally recommended that individuals with pacemakers keep their cell phones at least 6 inches (15 centimeters) away from the pacemaker to minimize any potential risk. In summary, while there was a time when cell phones could potentially interfere with pacemakers, advancements in technology have made this a very rare occurrence. It is always a good idea for individuals with medical devices to consult with their healthcare provider for personalized advice.

Radiofrequency energy (RF) from cell phones can interact with some electronic devices. This type of interference is called electromagnetic interference (EMI). For this reason, FDA helped develop a detailed test method to measure EMI of implanted cardiac pacemakers and defibrillators from cell phones.
