What precaution should a patient with a newly implanted pacemaker take when traveling?

When a patient has a newly implanted pacemaker, it is crucial to inform airport security about its presence. This precaution is necessary because the metal components of the pacemaker can trigger security alarms at checkpoints. Airport security personnel are trained to recognize medical devices, and by informing them in advance, the patient can avoid unnecessary delays or misunderstandings during security screening.

Additionally, informing security allows the personnel to use alternative screening methods if required, ensuring the safety and comfort of the patient. While wearing a medical alert bracelet can be beneficial for communication in emergencies, it does not address the specific concern of airport security. Similarly, having a note from the physician can be useful but is not as critical as directly communicating with security staff. Traveling strictly by car may limit options but is not a recommendation relevant to the typical context of travel that includes air travel. Thus, notifying airport security is the most appropriate and practical measure to ensure a smooth journey for someone with a pacemaker.
