"The Topology of Defibrillation"
October 22
3:05pm in LCB 225
Hundreds of lives are saved daily because of defibrillators, either
external defibrillators such as those used by paramedics or implanted
defibrillators. In spite of this obvious success, the mechanistic
explanation for this success is still unresolved and remains somewhat
controversial. In this talk, I will use topological arguments to
examine the method by which large scale virtual electrodes may
defibrillate cardiac tissue. I will show that the probability of
defibrillation success is bounded well below one, which contradicts
the experimental evidence. I conclude that some other mechanism must
be involved in defibrillation.
