RhythmStar gives cardiologists and clinical staff secure mobile access to their patients' cardiac monitoring information — anytime, on iPhone or iPad. The app provides a read-only view; it does not interpret data, generate alerts, or perform real-time patient monitoring. Cardiac monitoring information shown in the app is sourced from the user's monitoring service. RhythmStar supports multiple cardiac monitoring services and is restricted to credentialed medical providers. Accounts are provisioned by the clinical practice through their monitoring service — there is no public sign-up within the app. IMPORTANT: RhythmStar is for medical providers only and is not a patient-facing application. If you are a patient with questions about your cardiac monitoring, please contact your care team directly.
