“…It is well known that electromagnetic interference can pose a danger to patients with an ICD; 15,16 ventricular oversensing with subsequent delivery of inappropriate therapies, temporary or definitive suspension of all antitachycardia therapies or hardware damage can pose as possible mechanisms. 17–19 In other situations the use of magnets is desirable, for example when an ICD needs to be voluntarily inhibited from delivering therapies in surgical patients when tools that can interefere with the ICD are used.…”

Objective Small-scale observational studies have suggested that geomagnetic activity (GMA) may negatively correlate with the frequency of life-threatening arrhythmias. We investigated a potential relationship between implantable cardioverter defibrillator (ICD) therapies and daily GMA recorded in a large database. Patients and Methods The ALTITUDE database, derived from the Boston Scientific LATITUDE remote monitoring system, was retrospectively analyzed for the frequency of ICD therapies. Daily GMA was expressed as the planetary K-index and the integrated A-index and graded as Levels I – quiet, II – unsettled, III – active, and IV – storm. Results A daily mean of 59,468 ± 11,397 patients were monitored between 2009 and 2012. The distribution of days according to GMA was: Level I 75%, Level II 18%, Level III 5%, Level IV 2%. The daily number of ICD shocks received per 1000 active patients in the database was 1.29 ± 0.47, 1.17 ± 0.46, 1.03 ± 0.37, and 0.94 ± 0.29 on Level I, Level II, Level III, and Level IV days respectively; the daily sum of shocks and antitachycardia pacing (ATP) therapies was 9.29 ± 2.86, 8.46 ± 2.45, 7.92 ± 1.80, and 7.83 ± 2.28 on quiet, unsettled, active and storm days respectively. A statistically significant inverse relationship between GMA and the frequency of ICD therapies was identified, with the most pronounced difference between Level I and Level IV days (p < .001 for shocks, p = .008 for shocks + ATP). Conclusion In a large scale cohort analysis, ICD therapies were delivered less frequently on days of higher GMA, confirming the previous pilot data and suggesting that higher GMA does not pose an increased risk of arrhythmias using ICD therapies as a surrogate marker. Further studies are needed to gain an in-depth understanding of the underlying mechanisms.

“…Regarding classification of interference, some authors agreed to categorize the severity of each stimulation inhibition according to the PM dependence and the duration of this induced inhibition on CIEDs . In our study, short‐lasting stimulation inhibitions (≤ 3 pacings) were classified in the severe category.…”

Lahor-Soler E, Miranda-Rius J, Brunet-Llobet L, Sabat e de la Cruz X. Capacity of dental equipment to interfere with cardiac implantable electrical devices. Eur J Oral Sci 2015; 00: 000-000. © 2015 Eur J Oral SciPatients with cardiac implantable electrical devices should take precautions when exposed to electromagnetic fields. Possible interference as a result of proximity to electromagnets or electricity flow from electronic tools employed in clinical odontology remains controversial. The objective of this study was to examine in vitro the capacity of dental equipment to provoke electromagnetic interference in pacemakers and implantable cardioverter defibrillators. Six electronic dental instruments were tested on three implantable cardioverter defibrillators and three pacemakers from different manufacturers. A simulator model, submerged in physiological saline, with elements that reproduced life-size anatomic structures was used. The instruments were analyzed at differing distances and for different time periods of application. The dental instruments studied displayed significant differences in their capacity to trigger electromagnetic interference. Significant differences in the quantity of registered interference were observed with respect to the variables manufacturer, type of cardiac implant, and application distance but not with the variable time of application. The electronic dental equipment tested at a clinical application distance (20 cm) provoked only slight interference in the pacemakers and implantable cardioverter defibrillators employed, irrespective of manufacturer.

FUSE certification enhances performance on a virtual computer based simulator for dispersive electrode placement

This study demonstrated a new VEST educational module. Consistently high Likert assessment scores showed that users felt that the VEST module helped their understanding of dispersive electrode placement. Additionally, the study reflected a potential knowledge deficit in the safe use of dispersive electrodes in the surgical community, also demonstrating that even some exposure to the FUSE curriculum developed by SAGES provides increased awareness about dispersive electrode use.
