A device for detecting a state of imminent cardiac arrhythmia, relative to a normal state for a heart, in response to activity in nerve signals conveying information from the autonomic nerve system to the heart, contains a sensor body for sensing neural activity, a comparator with a threshold value forming a condition for the presence of an arrhythmia, the comparator emitting an arrhythmia-indicating output signal depending on whether neural activity meets the condition, and the sensor body being placeable in an extracardiac position for at least one of the sympathetic and vagus nerves. The sensor body directly senses activity in the nerve at that location in direct contact with the nerve. An implanted blood pressure sensing cuff also can be provided which generates signals indicative of blood pressure which can be evaluated in combination with the nerve signals for identifying the state of imminent cardiac arrhythmia.

An apparatus for detecting a condition indicative of imminent cardiac arrhythmia of a heart of a subject and for administering anti-arrhythmia therapy in response thereto, comprising: sensor means, placeable in an extracardiac position in said subject for directly sensing nerve signals conveying information from at least one member of the autonomic nerve system, of the group consisting of the sympathetic and vagus nerves of said subject, to said heart of said subject, said sensor means generating a single sensor signal corresponding to the sensed nerve signals; a comparator supplied with said single sensor signal and having a threshold value defining a condition indicative of an arrhythmia and said comparator emitting an output signal indicating a state of imminent arrhythmia dependent on a relation between said single sensor signal and said threshold value; and means for administering anti-arrhythmia therapy to said subject upon emission of said output signal indicating said state of imminent arrhythmia.
