Measurement and recording of Muscle Sympathetic Neural Activity (MSNA) using microneurography, will be applied to subjects who have been already implanted with a Moderato IPG delivering the BackBeat CNT and/or pacing signals. Several tests will be performed by experienced professionals to ensure the acquired sympathetic nerve signals arise from the targeted nerve source.
The Moderato Programmer will be then used to program different sets of CNT for several minutes with a several minutes interval between delivery periods. This delivery pattern is used will allow to acquire sympathetic nerve signals with and without CNT. Subject blood pressure, respiration and ECG data will be collected and recorded, both for safety and for evaluation of CNT dependent secondary indicators of sympathetic activity.
