What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Healthy (n=40). Intervention: Cardiio smartphone app vs. 12-lead electrocardiogram. Primary outcome: Accuracy of heart rate measurements (RMSE and correlation) (r=0.997, RMSE=1.03 beats/min, p=<0.001).

Resting and Postexercise Heart Rate Detection From Fingertip and Facial Photoplethysmography Using a Smartphone Camera: A Validation Study

Q: What are the key findings of this study?

The Cardiio smartphone app accurately measured heart rate at rest and after exercise using fingertip photoplethysmography (r≥0.994), while facial detection was less accurate post-exercise.

Does the Cardiio smartphone app accurately measure heart rate compared to a 12-lead ECG in healthy young adults at rest and after exercise?

Population

40 healthy adults aged 18 to 40 years underwent treadmill exercise to validate heart rate measurements using a smartphone-based photoplethysmography app against a continuous 12-lead ECG.

Intervention

Heart rate measurement using the Cardiio smartphone app via fingertip and facial photoplethysmography (PPG) at rest and after moderate- and vigorous-intensity exercise.

Comparator

Continuous 12-lead electrocardiogram (ECG) as the reference standard.

Outcome

Accuracy of heart rate measurements (agreement between ECG and PPG-estimated HR) evaluated by root mean square error (RMSE) and Bland-Altman plots.surrogate

Main Result

Effect estimate: r=0.997, RMSE=1.03 beats/min

p-value: p=<0.001

The Cardiio smartphone app provides accurate heart rate measurements at rest and after exercise using fingertip photoplethysmography, while facial detection is less accurate post-exercise due to body motion.

Limitations

Convenience sample of healthy young adults, which may limit generalizability
Method of HR detection using iPhone cameras may not apply to other smartphone cameras
Did not include patients with arrhythmia or other heart-related problems
Tested under standardized background lighting
Method of HR detection from fingertip and facial PPG using iPhone's front and back cameras may not apply to other smartphone cameras
