(Elsevier) An e-cigarette carried in the left breast shirt pocket of a patient with an implantable cardioverter-defibrillator (ICD) caused magnetic reversion, interrupting the ICD’s ability to detect and treat dangerous heart rhythm problems, clinicians report in HeartRhythm Case Reports, published by Elsevier. The patient was not aware that the e-cigarette has an integrated magnetic component, and it had suspended detection of heart rhythm problems by the ICD four times before he reported it to his healthcare team.
