Attorney, Agent or FirmInternational ClassA61N 001/36AbstractArrhythmia 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 sympathetic nerve activity and stimulating the afferent nerves may be implanted in a patient. Furthermore, the apparatus and method for the prevention of arrhythmia may be combined with apparatus for the treatment of arrhythmia through electric shock to facilitate treatment and prevent reoccurrence of arrhythmia.Other References
