Your Health on Your Sleeve: The Smartwatch Medical Makeover
Published Date: June 19, 2025
From luxury accessories to powerful medical allies, smartwatches have evolved into essential tools in today’s healthcare landscape. Their transformation from simple fitness trackers to medically relevant, health-monitoring wearables is not just a tech revolution but a paradigm shift in preventive healthcare. Today, these smart wearables can detect atrial fibrillation, track blood oxygen levels, alert users of abnormal heart rates, monitor sleep apnea, and even offer ECG readings — right from the wrist.
The Evolution of Smartwatches: From Gadgets to Medical Devices
The journey of wearable health tech began with basic pedometers and heart rate monitors in the early 2000s. Fitbit revolutionized the segment with its first tracker in 2009, igniting mainstream interest in digital fitness. Apple entered space with the Apple Watch in 2015, and with the release of Series 4 in 2018, featuring an FDA-cleared ECG sensor, smartwatches formally crossed into medical-grade territory.
This turning point marked a broader shift, where tech companies began prioritizing clinical-grade health data. Now, smartwatches are increasingly used not only by individuals but also by doctors, insurers, and researchers as tools for proactive health monitoring.
Current Practices: How Smartwatches Are Used in Healthcare Today
1. Cardiac Monitoring and Arrhythmia Detection:
One of the most widely recognized medical functions of smartwatches is atrial fibrillation (AFib) detection. AFib, a common irregular heartbeat condition, can lead to stroke and other heart complications if undiagnosed.
- Apple Watch Series 8 and Ultra: Apple’s latest smartwatches feature an FDA-cleared ECG app that records heart rhythms and notifies wearers of irregularities. Apple reports that this feature has identified AFib in millions of users globally.
- Withings ScanWatch: This hybrid smartwatch offers medical-grade ECG and SpO2 monitoring, blending traditional watch looks with clinical-grade sensors.
2. Blood Oxygen Saturation (SpO2) Monitoring:
SpO2 monitoring became especially prominent during the COVID-19 pandemic to track respiratory health.
- Fitbit Sense 2: Fitbit’s flagship device incorporates SpO2 sensors alongside skin temperature and electrodermal activity sensors, offering insights into stress and respiratory conditions.
- Garmin Venu 2 Plus: This watch provides SpO2 tracking and respiration rate metrics, empowering users to understand their fitness and wellness better.
3. Fall Detection and Emergency Alerts:
Smartwatches increasingly include fall detection features, automatically alerting emergency contacts or medical services if a hard fall is detected.
- Apple Watch Ultra: Equipped with advanced fall detection, it also offers international emergency calling and a built-in siren to attract attention.
- Samsung Galaxy Watch 5: Offers similar fall detection and SOS alerts, helping older adults live independently with peace of mind.
4. Chronic Disease Management:
For chronic disease patients, continuous health data provides valuable insights.
- Dexcom G7 Integration: Smartwatches like Fitbit and Apple Watch now integrate with continuous glucose monitors (CGMs) such as the Dexcom G7, allowing diabetics to monitor blood sugar levels in real-time on their wrists.
- Blood Pressure Monitoring: Devices such as the Omron HeartGuide have received FDA clearance for clinically accurate blood pressure monitoring.

Integration With Telemedicine and Remote Patient Monitoring
Smartwatches feed continuous data to clinicians and integrate with platforms like:
- Apple Health → Epic EHR
- Fitbit → Google Health
- Samsung → MyChart integrations
The integration of remote patient monitoring (RPM) with telehealth platforms expands telemedicine deployment through reimbursement opportunities, specifically through CPT codes 99453 and 99454. These codes, which cover initial RPM setup and continuous monitoring, provide financial incentives for healthcare providers to implement and expand telehealth services.
Data Privacy and Security in Smartwatch Health Tech
With smartwatches collecting continuous, sensitive biometric data, data governance becomes critical.
- HIPAA compliance in the U.S.
- General Data Protection Regulation (GDPR) in the EU requires informed consent and data minimization.
- Users often do not realize their health data may be shared with insurers or advertisers.
Consumer Tip: Before synchronizing your watch to third-party apps, always review the app’s privacy policy.
Recent Product Launches Transforming Wearable Health Tech
The smartwatch industry continues to innovate rapidly with new product launches pushing medical boundaries.
