Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="abs1-1" sec-type="section"> <title> <italic>Introduction: Methods:</italic> </title> <p>We compared the problems or complications associated with electrodiagnostic testing in 77 patients with implanted cardiac devices. Thirty tests were performed after magnet placement, and 47 were performed without magnet application.</p> </sec> <sec id="abs1-2" sec-type="section"> <title> <italic>Results:</italic> </title> <p>All electrodiagnostic tests were performed safely in all patients without any serious effect on the implanted cardiac devices with or without magnet placement. A significantly higher number of patient symptoms and procedure changes were reported in the magnet group (<italic>P</italic> &lt; 0.013). No statistical difference was found in the testing difficulty or ECG changes.</p> </sec> <sec id="abs1-3" sec-type="section"> <title> <italic>Conclusion:</italic> </title> <p>The magnet group patients had an approximately 11‐fold greater risk of symptoms than those in the control group. Our data do not support a recommendation that magnet placement is necessary for routine electrodiagnostic testing in patients with implanted cardiac devices, as long as our general and specific guidelines are followed.
