Comparison of Continuous Sternal ECG Patch Monitors (Carnation and Zio) Trial

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.

Inclusion Criteria:

- Syncope of uncertain etiology or

- Pre-syncope of uncertain etiology or

- Palpitations of uncertain etiology or

- Management of known AF/SVT patients

Exclusion Criteria:

- Any dermatitis or infected skin over the sternum (Carnation patch) or left upper
anterior thorax (Zio patch).
