Study Scope and Process
This study involves a 6 minute walk test protocol designed to capture ECG rhythm before, during and after the routine.
Using the VivaLNK companion mobile app customized for the protocol and the wearable ECG monitor, data from subjects across multiple locations are captured and delivered to a central location for analysis.
VivaLNK web services then consolidates data across each site for retrospective analysis.

Challenges Addressed
- Multi-site data consolidation
- Customized app protocol
- Network disconnections
- ECG stability during walk
Parameters Captured
- Raw ECG rhythm
- Stabilized heart rate
- RR-interval
- 3-axis accelerometer
