FIGURE 2.

Timeline of continuous and spot-check measurements performed by ICM and mHealth. A seven-day ECG Holter was used in the first month. At the end of the second month, the ICM was inserted, and the use of PPG-based mHealth was initiated. Green bars indicate a sinus rhythm, red bars indicate an AF episode, dark red bars indicate a symptomatic AF episode as reported in the mHealth app, blue bars indicate insufficient data quality, and the black bar indicates the ablation. ICM, insertable cardiac monitor; mHealth, mobile health.
