Investigation of the effects of various devices such as pacemakers and ICDs.

Investigation of the effects of various devices such as pacemakers and ICDs.

We will prepare a report that measures and investigates the electromagnetic fields generated by various devices, explaining the potential impact on pacemakers and other devices, as well as possible countermeasures.

Each equipment manufacturer has no method to conduct tests to determine whether their products affect pacemakers, ICDs, etc., and is unable to provide accurate information in the attached documents and user manuals. As a result, they either prohibit or restrict the use of their devices, or if there have been no past incidents, they may choose not to include warning labels. Our company has developed guidelines for electromagnetic effects on pacemakers and ICDs based on electromagnetic impact studies previously conducted by the Ministry of Internal Affairs and Communications and the Ministry of Health, Labour and Welfare, as well as our own electromagnetic impact tests conducted in collaboration with the Electromagnetic Environment and Electromagnetic Wave Protection Product Evaluation Association (EAE). In accordance with these guidelines, we will conduct electromagnetic field measurement surveys of the equipment handled by companies and prepare reports that clearly explain to users the potential impacts on pacemakers and ICDs, as well as points of caution and countermeasures. Additionally, based on the report, it is possible to obtain the electromagnetic safety evaluation mark "EAE Mark." Once the evaluation mark is obtained, the safety of the product concerning pacemakers, etc., will be publicly announced. In the event of discrepancies in safety evaluations that affect pacemakers, EAE will conduct an investigation and provide compensation to pacemaker users.
