Overview

Withings Scan Monitor is an AI-powered health monitoring tool integrated into Withings’ smart devices, such as the Body Scan connected health station and ScanWatch hybrid smartwatches. It provides medical-grade data for cardiovascular health assessment and remote patient monitoring. The Scan Monitor enables users and healthcare professionals to record electrocardiograms (ECG) for the detection of atrial fibrillation (AFib) and measure heart rate. When integrated into the Body Scan, it offers a 6-lead ECG, vascular age assessment, nerve health score, and segmental body composition analysis. In the ScanWatch, it provides a single-lead ECG and measures blood oxygen saturation (SpO2). Data is automatically synchronized to the Withings Health Mate mobile app, allowing for detailed insights, trend tracking, and easy sharing with clinicians.

Withings Health Solutions offers a comprehensive remote patient monitoring (RPM) platform for healthcare providers, integrating these devices to facilitate continuous access to patient health data, streamline billing for CPT codes, and enhance patient engagement through an AI-powered digital assistant.

What Physicians Need to Know

ECG/EKG Analysis Capability
The Withings Scan Monitor records a single-channel ECG (similar to lead I) and the Scan Monitor 2.0, when combined with the Withings Body Scan, records a 6-lead ECG. It detects the presence of Atrial Fibrillation (AFib) and sinus rhythm, calculating heart rate, P wave duration, PR interval, QT interval, QT corrected interval, and QRS duration. Results are classified as Sinus Rhythm, Atrial Fibrillation, or Inconclusive. Clinical-ready PDF reports can be generated for physician review.
Arrhythmia Detection Accuracy
The Scan Monitor software demonstrated 98.16% sensitivity in classifying AFib and 97.20% specificity in classifying sinus rhythm in classifiable recordings from public databases. In clinical validation studies, the ScanWatch (incorporating Scan Monitor) showed 96.3% sensitivity for AFib and 100% specificity for normal sinus rhythm on conclusive recordings, with approximately 19.5% of recordings being inconclusive. Another study reported 76% sensitivity and 99% specificity for AFib detection using the automated algorithm, with cardiologist interpretation of iECGs from the device achieving 98% diagnostic accuracy. The device can identify up to 10 arrhythmias, primarily focusing on AFib, but cannot detect arrhythmias other than AFib.
Cardiac Monitoring Integration
Data is transferred to the Withings app (Health Mate app) via Bluetooth LE. Withings offers a 'Cardio Check-Up' service (with a Withings+ subscription) where board-certified cardiologists review ECG data and other health information within 24 hours. Withings Remote Patient Monitoring (RPM) integrates with various EHR platforms for seamless data synchronization, device ordering, billing, and alerts. It also provides Public API, Cellular Integration, and SDK Integration for developers, and integrates with platforms like Fitrockr and Validic.
AHA/ACC Guideline Alignment
The Withings Scan Monitor (and ScanWatch) is FDA-cleared. Its clinical validation studies compare its performance against a 12-lead ECG, considered the industry gold standard. The software's accuracy in classifying ECG recordings was tested according to the IEC 60601-2-47 standard.
Physician Tip

The Withings Scan Monitor, particularly the ScanWatch models, offers a convenient tool for patients to monitor their heart rhythm and detect potential Atrial Fibrillation (AFib) at home. While it provides valuable single-lead (or 6-lead with Body Scan) ECG data and automated AFib detection, clinicians should be aware of its limitations, including a percentage of inconclusive readings and its inability to detect arrhythmias other than AFib or ischemic heart conditions. The 'Cardio Check-Up' service, offering cardiologist review of ECGs, can be a useful adjunct for interpreting ambiguous readings or identifying other potential cardiac irregularities. Encourage patients to share PDF reports of their ECGs for comprehensive review. The device serves as a screening tool and should not replace traditional diagnostic methods or professional medical advice.

Withings devices, including the Scan Monitor, integrate seamlessly with the Withings Health Mate app for data visualization and management. For healthcare providers, Withings offers Remote Patient Monitoring (RPM) solutions with integration capabilities for Electronic Health Record (EHR) platforms, facilitating data synchronization and alert management. Developers can leverage Public API, Cellular Integration, and SDK Integration options to incorporate Withings health data into other applications and systems. Compatibility with third-party platforms like Fitrockr and Validic further enhances its utility in broader health ecosystems. The ability to connect with IFTTT also allows for custom automation workflows.

Frequently Asked Questions

The Withings Scan Monitor, particularly with devices like the Body Scan and ScanWatch 2, uses AI to analyze various health metrics such as 6-lead ECG for AFib detection, segmental body composition, vascular age, and nerve activity. Through the Withings+ subscription, AI-powered insights offer personalized health advice, smart trends, and a Vitality Indicator to help users and physicians track and improve health outcomes.
The Withings Scan Monitor 2.0, integrated into the Body Scan, has received FDA clearance for detecting atrial fibrillation using its 6-lead ECG technology, making it the first health station to achieve this. The Scan Monitor 1.0, used in the ScanWatch, also has FDA clearance for 1-lead ECG and SpO2 measurements for AFib detection.
A notable limitation is the occurrence of inconclusive ECG recordings, which can be as high as 20.2% for the Scan Monitor and 19.5% for the ScanWatch 2 in clinical settings. The devices are not continuous AFib monitors and may not detect all instances of AFib, with heart rate measurements on the ScanWatch occurring every 10 minutes, potentially missing short-term changes.
The Withings Body Scan device is priced around $399.95 to $499.95, and accessing its full AI-powered features and advanced insights typically requires a Withings+ subscription, which costs approximately $9.95 per month or $99.50 annually. Withings also offers remote patient monitoring solutions for healthcare professionals, which can support CPT code billing.
Alternatives for remote patient monitoring include platforms like Xealth, Biofourmis Care, Validic Impact, and Rimidi's Disease Management Platform, which offer comprehensive solutions for clinicians. For personal health tracking, devices such as the Apple Watch, WHOOP, and Oura Ring also provide various health insights, though their medical clearances and specific features may differ.
Withings offers remote patient monitoring solutions designed to integrate health data, allowing for transparent access to patient metrics and the potential for automatic upload of RPM service charges into EHR systems. This aims to streamline claim creation and provide audit reports for compliance.
