NCT03087084

Brief Summary

The purpose of this prospective, non-randomized, single-arm, research study is to evaluate the accuracy of acutely extracting respiratory rate and tidal volume from implanted cardiac device impedance in subjects with heart failure. In addition, to assess the feasibility of extracting respiratory rate from device EGM under various conditions.

Outcome Measures

Primary Outcomes (1)

  • Accuracy of extracting respiratory features from intrathoracic impedance acutely in subjects with heart failure

    Impedance-derived respiratory rate during different breathing patterns

    Implant

Secondary Outcomes (1)

  • Assess the feasibility of extracting respiratory rate from EGM under various conditions

    Implant and 2 months follow-up

Study Arms (1)

Cardiac Pacing and Impedance Measurement system

EXPERIMENTAL
Device: Cardiac Pacing and Impedance Measurement system

Interventions

Subjects indicated for Implantable Cardioverter Defibrillator or Cardiac Resynchronization Therapy Defibrillator device implant will be requested to perform some respiratory manoeuvres while impedance and electrogram signals are recorded by the system

Cardiac Pacing and Impedance Measurement system

Eligibility Criteria

Age18 Years - 99 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject must have heart failure and be undergoing implant of a new or replacement/upgrade Medtronic dual-chamber Implantable Cardioverter Defibrillator or Cardiac Resynchronization Therapy Defibrillator device for approved indications;
  • Subject must be implanted with an right ventricle lead that supports bipolar pacing and sensing (i.e. a true bipolar defibrillation lead);
  • Subject must receive a light conscious sedation or no sedation where breathing maneuvers can be performed and evaluated during the implant;
  • Subject must be willing to provide Informed Consent for their participation in the study;
  • Subject must be ≥ 18 years of age.

You may not qualify if:

  • Subjects who are unable or unwilling to voluntarily participate in any visit required by the study and to provide consent;
  • Subject has congenital heart disease;
  • Subject has a tachyarrhythmia (atrial and/or ventricular) at the time of enrollment and a cardioversion will not be attempted prior to the research procedure;
  • Subject has unstable coronary artery disease;
  • Subject requires cardiac pacing at rest for rate support;
  • Subject presents any concomitant conditions which in the opinion of the investigator would not allow a proper execution of the respiratory exercises as per protocol;
  • Subject presents any concomitant condition which in the opinion of the investigator would not allow a safe participation in the study;
  • Subject is pregnant or breast feeding;
  • Subject is legally incompetent;
  • Subject is enrolled in a concurrent study that may confound the results of this study without documented pre-approval from Medtronic study manager.
