¿Puede un smartwatch detectar una arritmia?
.
En fibrilación auricular, la evidencia indica que sí. Una revisión sistemática y metaanálisis con 26 estudios y más de 17.000 pacientes mostró sensibilidad cercana al 95% y especificidad del 97%. Los modelos basados en PPG y ECG demostraron rendimiento comparable.
.
El punto no es técnico, es médico: precisión diagnóstica no equivale a impacto en resultados. En poblaciones con baja prevalencia disminuye el valor predictivo positivo, aumentan las alertas falsas y la indicación terapéutica sigue dependiendo del riesgo tromboembólico y hemorrágico individual.
