Can those with a heart pacemaker use a walkie-talkie?
Pacemakers are devices used to give regular electrical signals to the heart when the natural pacemaker of the heart (sinus node) has ceased functioning or when the signals from the sinus node are blocked so that they do not reach all chambers of the heart. Since pacemakers have electrical circuitry, they can be interfered by strong electromagnetic waves. Hence it will be ideal that a walky-talky is not placed very near the location where the pacemaker is implanted. If we can keep it sufficiently away, it can be prevented from interfering the pacemaker function. Many of the modern day pacemakers have built in filters to avoid electromagnetic interference.
