The device maintains medical-grade arrhythmia detection while adding sleep monitoring features. A survey of 17 participants showed 88% intend to continue using the system, and 78% were satisfied with the overall experience.","whyItMatters":"The device aims to combine heart monitoring, sleep apnea screening, and stress tracking in a single at-home wearable, with survey results showing high user intent for continued use.","webCardHtml":"\u003cp\u003eThe device maintains the form factor of the existing Home Heart Dock pro-a small chest-attached ECG that records over nine hours-but adds sleep-focused analysis: it tracks heart rate trends, chest movement to measure respiratory pressure, sleep position via posture, and snoring sounds. Kokoromil says this allows single-device screening for both cardiac disease risk and sleep apnea syndrome or stress from autonomic nervous system activity.\u003c/p\u003e\u003cp\u003eThe verification experiment, conducted as part of Yamanashi Prefecture\u0026#39;s demonstration support project, drew 17 respondents. Of those, 71% found the device very or somewhat easy to attach and remove, 65% said starting measurement was easy, and 78% were satisfied overall. User comments pointed to an increased willingness to act on health data: one respondent said seeing poor sleep quality made them positive about lifestyle changes. The company plans to address feedback about skin burden from electrode adhesive by switching to new materials, aiming for general release after further improvements.\u003c/p\u003e","blueskyPost":"Kokoromil completes first verification of 'kokolog MD', a wearable ECG that adds sleep apnea and stress screening to arrhythmia detection. 88% of test users said they want to keep using it.","twitterPost":"Kokoromil completes first verification of its next-gen wearable ECG 'kokolog MD'.
