Primary Outcome Measures:
  • ECG signal quality [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    ECG signal quality = scoring the ability of each system to record electrical activity from the atrium (P-waves). The Physician Event Committee will independently score the P-waves from all recordings, using the following scale: Excellent, Good, Fair, Poor, Non-existent.

Secondary Outcome Measures:
  • Device comfort [ Time Frame: 14 days ] [ Designated as safety issue: Yes ]
    Secondary outcome measures will include Human Factors performance of the 2 systems, which will be scored and compared in the following areas and duration of patch adherence: skin irritation, comfort, contact and stability.

Estimated Enrollment: 50
Study Start Date: July 2016
Estimated Study Completion Date: January 2017
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Detailed Description:
The purpose of this research is to confirm the clinical value of a new P-wave sensitive recording vector combined with an easy-to-use long-term cardiac rhythm monitoring patch system, the CarnationTM Ambulatory Monitoring (CAM) System. The P-wave is a critical aspect of the electrocardiogram and a key finding for proper arrhythmia diagnosis. The CAM system is optimized for both ease of use and for maximum P-wave clarity for arrhythmia diagnosis.
