Further study details as provided by St. Jude Medical:

Primary Outcome Measures:
  • The primary endpoint is intended to demonstrate that the number of departures from the stability zone that are unrelated to a pulmonary congestion event (False Positive) per patient-year of follow-up is less than 1.5. [ Time Frame: 6-months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Sensitivity of the index to detect events will be calculated as the proportion of events with a related departure. [ Time Frame: 6-months ] [ Designated as safety issue: No ]
