Discussion

Randomized trial shows smartphone application improves detection rates of atrial fibrillation, suggesting effective screening method.

Atrial fibrillation detection was numerically higher in the intervention group compared to the sham group.
Arrhythmia was detected in 32 patients, including 20 in the intervention group and 12 in the sham group.
The smartphone app utilized photoplethysmography to identify potential atrial fibrillation cases.
Asymptomatic atrial fibrillation detection was notably higher in the intervention group, though not statistically significant.

Reichl et al. (2025) studied this question.
