Why the study?

Wearables are increasingly used to monitor heart rate, but their usefulness for continuous heart rate analysis in research or clinical settings is questionable.

Does heart rate monitoring using Apple Watch and Polar Vantage agree with gold-standard ECG in healthy university students during different physical activities?

Comparison

Apple Watch and Polar Vantage watch vs gold-standard ECG across four physical activity situations

Design

Implication

Supports cautious Apple Watch use for HR monitoring during activity in healthy young adults; leaves open broader validation for Polar devices.

Structured PICO

Does heart rate monitoring using Apple Watch and Polar Vantage agree with gold-standard ECG in healthy university students during different physical activities?

P
Population
18 university students (10 men, 8 women), mean age 22 ± 2.45 years old.
I
Intervention
Heart rate monitoring using Apple Watch S6 and Polar Vantage M2 during 5-min periods of lying, sitting, standing, and walking.
C
Comparator
Beat-to-beat heart rate obtained by a reference ECG system (Biopac MP36).
O
Outcome
Level of agreement between wearables and ECG in heart rate measurement across different body positions, physical activity levels, and time scales.surrogate

Photoplethysmography-based wearables like the Apple Watch provide accurate heart rate averages at rest, but their accuracy decreases during physical activity and for continuous short-epoch analysis compared to ECG.
