Abstract
Methods and apparatuses are provided for assisting with the diagnosis, monitoring, and/or treatment of patients that are suffering from asymptomatic heart failure or may be susceptible to asymptomatic heart failure. The methods and apparatuses can be implemented with implantable devices. In certain implementations, a method is provided which includes sensing muscle sympathetic nerve activity using at least one nerve sensing electrode that is in electrical contact with a patient's efferent muscle-nerve structure, acquiring a muscle sympathetic nerve activity signal from the sensed nerve activity using a nerve activity sensing circuit operatively coupled to the nerve sensing electrode, and analyzing the nerve activity signal for changes in nerve burst activity indicative of the presence and/or severity of asymptomatic heart failure.
