Claim:
1. An implantable medical device, comprising: a sensor configured to sense atrial arrhythmia vulnerability data; a therapeutic stimulator configured to deliver an electrical signal to provide vagal stimulation; and means for controlling the therapeutic stimulator, the controlling means configured to receive sensed atrial arrhythmia vulnerability data and to control the therapeutic stimulator to reduce the vagal stimulation to limit atrial proarrhythmia using the sensed atrial arrhythmia vulnerability data, wherein the sensed atrial arrhythmia vulnerability data includes signs or symptoms of increased atrial vulnerability including at least one of: sensed changes in atrial arrhythmia etiology, relative timing of atrial arrhythmia related to the introduction or delivery of stimulation therapy; or sensed increases in premature atrial complexes (PACS), PAC trains or atrial flutter.
