The increasing use of microprocessors and associated software in both implanted and external medical devices poses special analytical challenges.

Programmable pacemakers, long-term portable ECG recorders, and ECG arrhythmia detection monitors, for example, contain cardiac arrhythmia detection software. Examination of such devices is difficult, especially because failures are rare and transient.

Our investigations of accidents related to microprocessor-based devices take a broad approach, seeking both hardware and software problems.
