This presentation will cover the basics of the cardiac conduction system and the pacemakers and defibrillators used to correct cardiac arrythmias. A circuit block diagram of a typical pacemaker system will be presented, as well as a discussion of the ASIC processes being used. Some new developments in implantable cardiac devices will also be discussed. Special emphasis will be placed on failure analysis of the ICs used in their circuitry.
Prasanna Paralkar is a Member of Technical Staff at Micro Systems Engineering, Inc., a subsidiary of Biotronik Inc. in Lake Oswego, Oregon. He received his M.Sc. in Physics (semiconductor electronics) from the University of Mumbai and his M.S. in Electrical Engineering from Utah State University. He joined Bourns Inc. in 1989, where he not only designed surge protection circuits for telecommunication markets but also managed and implemented all stages of processing and testing these devices. He received a patent for a surge protection device design using thick film resistors. He joined Micro Systems Engineering Inc. in 1997, where his work involves yield, reliability and failure analysis of ASICs for implantable pacemakers and defibrillators.
