Waveform Flexibility: The Present and Future Solution for Clinically Effective Defibrillation

  • M. W. Kroll
Conference paper


The monophasic shock defibrillates primarily by capturing cardiac myocytes regardless of their phase. Since most cells are in phases 2 and 3 during fibrillation, the shock must be strong enough to cause a new activation potential even though these cells are refractory in the usual sense of the word.
