Respiration Patterns With Impedance in LINQ

Inclusion Criteria: * Suspected arrhythmia Diastolic Heart Failure and/or in Renal Failure. * Chronic Kidney Disease (CKD) in Stage 5 (GFR = \<15 mL/min). * Diastolic Heart Failure in class II and class III (class IV to be considered in end stage and non-reversible). * Willing to sign the informed consent form. * Greater than 18 years of age. Exclusion Criteria: * Enrolled in another study that could confound the results of this study, without documented pre-approval from a Medtronic study manager. * Significant respiratory diseases such as COPD or pulmonary hypertension. * Frequent arrhythmias, including PVC's. * Known systolic heart failure. * Recent infection. * Allergenic or rejection reaction to materials used in incision/insertion tools, Reveal LINQ™ ICM exterior or incision closure method. * Active implanted cardiac medical device (e.g. IPG, ICD, CRT, etc). * Not suitable for Reveal LINQ™ implantation (e.g., severe cachexia, dermatologic conditions of the skin) or any concomitant condition which in the opinion of the investigator would not allow a safe participation in the study. * Body conditions that would complicate accurate measurement of respiratory efforts with an external device deployed around the chest. * Not able to take the postures as necessary for the study protocol and not able to walk continuously for a period of 6 minutes. * Any concomitant condition which in the opinion of the investigator would not allow a safe participation in the study.
