Electromagnetic Fields

3.0K
Electric fields generated by static charges, often referred to as electrostatic fields, are characteristically different from electric fields created by time-varying magnetic fields. While the former is a conservative field, implying that no net work is done on a test charge if it goes around in a complete loop in the field, the latter is, by definition, not a conservative field; net work is done, and it is proportional to the rate of change of magnetic flux.
However, the observation of...

Applications of EMF Measurements

36
Electromotive force (EMF) measurements have a broad range of applications in various fields, including chemistry and physics. The electrochemical series, an arrangement of elements in order of their standard electrode potentials, can be determined through EMF measurements. Elements with lower standard potentials can reduce ions of elements with higher standard potentials.The standard cell potential, E°, allows for the calculation of the standard reaction Gibbs energy, ΔG°, and...

Atomic Emission Spectroscopy: Interference01:30

Atomic Emission Spectroscopy: Interference

729
In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

Summary

Environmental electromagnetic interference (EMI) can affect cardiac implantable electronic devices (CIEDs). A case study identified AC current leakage in a swimming pool as the source of an unusual EMI signal in a patient with an implantable cardioverter defibrillator (ICD).

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Environmental Health

Background:

  • Cardiac implantable electronic devices (CIEDs) are susceptible to electromagnetic interference (EMI) from environmental sources.
  • Despite improved lead design, EMI events in CIED patients are increasingly reported.
  • Swimming pools have been an infrequent source of inappropriate device therapies.

Purpose of the Study:

  • To report a unique case of EMI in a patient with an implantable cardioverter defibrillator (ICD).
  • To identify the environmental source of the detected EMI signal.
  • To highlight potential risks associated with electrical systems in recreational water environments.

Main Methods:

  • Case presentation of a 64-year-old male with a CIED experiencing an unusual EMI signal.
  • Signal analysis to determine the characteristics and origin of the interference.
  • Investigation of the patient's environment, specifically a swimming pool, for potential EMI sources.

Main Results:

  • An anomalous EMI signal was detected in the patient.
  • The source of the EMI was traced to an alternating current (AC) leak within the swimming pool's electrical system.
  • This environmental electrical fault caused the observed interference in the patient's ICD.

Conclusions:

  • Environmental electrical faults, such as AC current leaks in swimming pools, can pose a risk to patients with CIEDs.
  • This case underscores the importance of thorough environmental assessments when investigating EMI in CIED patients.
  • Awareness and mitigation of such electrical hazards are crucial for patient safety and device function.
