The automatic implantable cardioverter-defibrillator: evaluating suspected inappropriate shocks
Journal of the American College of Cardiology
|May 1, 1986
Summary
Diagnosing inappropriate shocks from implanted defibrillators can be challenging. Using phonograms with a magnet noninvasively confirmed sensing problems in two patients, aiding diagnosis of device malfunctions.
Area of Science:
- Cardiology
- Biomedical Engineering
- Medical Device Technology
Background:
- Implanted defibrillators (ICDs) can deliver inappropriate shocks due to sensing issues.
- Lead fractures and sensing of extraneous signals (e.g., pacemaker stimuli) are known causes.
- Accurate diagnosis of these sensing problems is crucial for patient safety.
