The available measurement devices of the study. The devices used in the measurements: (1) our custom Holter monitor (on the left, used in CT-A), (2) AliveCor’s phone ECG and patch (in the middle, used in HM-C), and (3) a 3D printed mounting for Android device (used in HM-B, not the cover, on the right) for improved contact and to avoid the sliding of the phone
