Every 90 seconds, someone in the US experiences sudden cardiac arrest (SCA). Nine out of ten victims die. Survivors receive implantable defibrillators (ICDs) so that subsequent SCA events are not fatal. ICDs monitor cardiac electrograms and perhaps other biological signals 24/7, always on the alert for potentially fatal tachyarrythmia so that life-saving therapy can be delivered quickly. Algorithms must be fast, accurate and efficient, yet must run on an 8-bit processor. We will examine the defibrillator detection problem, some of the solutions and their performance.


Dr. Mark Brown is a senior principal scientist working in cardiac rhythm and disease management research at Medtronic where he has been employed for 19 years. He holds a BS in Physics from Hope College, an MS in CICE and MS and PhD in Bioengineering from the University of Michigan. His areas of research are focused on the clinical applications of signal processing, sensing, detection and therapy for cardiac arrhythmias and methods of identifying patients at risk of cardiac arrhythmia.
