History of Cardiac Pacing

In 1954 Dr. C. Walton Lillehei, a cardiac surgeon at the University of Minnesota, made advances in the treatment of the blue baby syndrome, but on October 31, 1957, a 3-hour power outage in Minneapolis rendered these generators useless because the wards had no backup electrical generators.

Optimization of Wireless Power Transfer Systems with Multiple Transmitters and Receivers

This work aims to bridge the gap by providing optimization methods for general WPT systems, consisting of an arbitrary number of transmitters and receivers, in order to determine the absolute maximum achievable performance of said systems.

The Exterior Potential and the Electrocardiogram

This chapter analyzes the small electrical potential produced outside a nerve or muscle fiber, often described using a multipole approximation, and develops a model for the electrocardiogram based on a current-dipole source.

The Future is Now

Scholarship in the history and sociology of technology has convincingly demonstrated that technological development is not inevitable, pre-destined or linear. In this paper I show how the creators of

Understanding the history of early PM and ICD device development, recognizing the importance of the clinical data that was required to launch the current “era” of exponential device use, and appreciating the challenge of maintaining device innovation without sacrificing device reliability are important lessons that may offer insights into future cardiovascular device development.
