May support individualized in vivo testing of pacemaker interference thresholds; leaves open clinical relevance to real-world electromagnetic exposure.
Does injected 50 Hz alternating current affect the function of implanted unipolar VVI pacemakers?
Injected 50 Hz alternating current safely and reproducibly tests the sensitivity of implanted pacemakers to external interference, causing reversion to interference mode at 29-250 microA.
Kaye et al. (1988) studied this question.
