Conditions
Outcome Measures
Primary Outcomes (1)
Mean Change in Pulmonary Artery Pressure (PAP) Due to Change in Posture
Posture defined as lying left side down compared to baseline supine
Same day as enrollment (during office visit, maximum of 30 minutes after baseline masurement)
Secondary Outcomes (2)
Change in PAP During Change in Respiration
Same day as enrollment (during office visit, maximum of 30 minutes after baseline measurement)
Change in PAP as Measured After Mild Exertion Compared to Initial Baseline PAP at Rest.
Same day as enrollment (during office visit, maximum of 10 minutes after baseline measurement)
Study Arms (1)
All participants
OTHERAll participants enrolled in a single arm to evaluate effect of variables (posture, respiration, exertion) on pulmonary artery pressure (PAP)
Interventions
Cardiac Monitor with LINQ™ HF Investigational RAMware download
Eligibility Criteria
You may qualify if:
- Investigator believes the patient's condition is sufficiently stable to safely participate in the study procedures
- Subject is currently implanted with a commercially available pulmonary artery pressure sensor and device communication has been reliable (recent history of successful communications with patient communication system)
You may not qualify if:
- Subject has a history of primary PAH
