Symbols in the table
| ※Danger (dangers are indicated by symbols) | |
| - | No impact |
|---|---|
| ! | Correct use of the equipment is required. |
| ▲ | Danger (pacemakers, ICDs, etc. may function improperly, but there is little risk of serious health problems) |
| ☆ | Contraindications (There is a high possibility that pacemakers, ICDs, etc. may function improperly, which may result in serious health problems) |
| ※Impact（Impact on pacemakers, ICDs, etc. are shown with symbols） | |
| I | Pacing is suppressed (the number of heartbeat signals from pacemakers, ICDs, etc. is reduced). It is necessary to leave the area as soon as possible. |
|---|---|
| T | Unnecessary stimulation occurs. Demand function is lost, and conflict between the pacemaker, ICD, etc. and the patient's own pulse may occur. It is necessary to leave the area as soon as possible. |
| R | The settings of the pacemaker, ICD, etc. will change and will not return to their original state. You will need to go to the hospital immediately and have the pacemaker, ICD, etc. reset. |
| D | Pacemakers, ICDs, etc. may stop functioning or be destroyed. |
