Measurement and Data Transmission Validity of a Multi-Biosensor System for Real-Time Remote Exercise Monitoring Among...

Area of Science:

• Cardiovascular Technology
• Digital Health Monitoring
• Physiological Measurement

Background:

• Remote telemonitoring offers potential for managing coronary heart disease (CHD) and atrial fibrillation (AF) patients during physical activity.
• It may enhance exercise-based cardiac rehabilitation (exCR) and assess heart rate control interventions.

Purpose of the Study:

• Evaluate the measurement validity and data transmission reliability of a remote telemonitoring system.
• Assess system performance in individuals with sinus rhythm and AF during various activities.

Main Methods:

• Participants in sinus rhythm and AF performed simulated daily activities and exercises.
• Remote system's heart rate and respiratory rate were compared to ECG and indirect calorimetry.
• Wireless data transmission loss was calculated across system components.

Main Results:

• Small, statistically significant biases were observed for heart rate and respiratory rate measurements.
• Excellent measurement reliability (rho, ICC) was generally found, except for respiratory rate in AF participants.
• Minimal data loss (<5%) occurred when all components were active; network instability caused some server-side loss.

Conclusions:

• The telemonitoring system demonstrated sufficient validity for remote heart and respiratory rate monitoring during exercise.
• Remote exercise monitoring can augment exCR and heart rate management by enabling tailored, remote patient care.
