Using a Wearable ECG Monitor for the Six Minute Walk Test

The Six-Minute Walk Test (6MWT) is a practical, simple test that measures the distance a patient can quickly walk on a flat, hard surface in a span of six minutes This globally recognized evaluation involves all systems during exercise, from the pulmonary and cardiovascular systems to peripheral circulation, blood, neuromuscular units, and muscle metabolism. The test doesn't require exercise equipment or advanced training for patients making it easy for clinicians to administer.

Study Scope and Protocol

This multi-site, multi-country study involves a six-minute walk test protocol designed to capture ECG rhythm and heart rate before, during and after the routine, while the patient walks a 90 foot designated path.

This study leveraged Vivalink’s Biometric Data Platform and the wearable ECG monitor to analyze patient heart rate changes throughout the routine.
