In a method and apparatus for defibrillating a heart in fibrillation, the onset of fibrillation of the heart is detected, and a biphasic waveform having only a first phase and a second phase is applied to the fibrillating heart. Each phase of the waveform is characterized by a predetermined time dur ...

Raymond E Ideker, Xiaohong Xhou: Method and apparatus for the prevention of arrhythmia by nerve stimulation. Duke University, Bell Seltzer Park & Gibson, June 4, 1996: US05522854 (243 worldwide citation)

Arrhythmia is prevented by detecting a high risk of arrhythmia and then stimulating afferent nerves to prevent the arrhythmia. By monitoring the sympathetic and parasympathetic nerve activity of a patient the risk of arrhythmia may be assessed. An apparatus for monitoring of parasympathetic and symp ...
