What Physicians Need to Know
ECG/EKG Analysis Capability
The Verily Study Watch is a prescription-only device with FDA 510(k) clearance for its on-demand, single-channel ECG feature, allowing it to record, store, transfer, and display ECG rhythms. It utilizes both photoplethysmography (PPG) to detect subtle changes in heart rhythm and prompts users to take a single-lead ECG for confirmation if atrial fibrillation is suspected. The results are then analyzed by a cardiographic technician before being shared with the participant's physician.
Echocardiography AI Features
The Verily Study Watch does not have echocardiography AI features. However, walking measures collected by the Study Watch have shown correlation with echocardiographic cardiac-remodeling and dysfunction indices in early-stage heart failure.
Arrhythmia Detection Accuracy
The Verily Study Watch has demonstrated high accuracy in detecting atrial fibrillation (AFib) episodes through continuous monitoring using a deep neural network algorithm trained on real-world data. A clinical study published in the Journal of the American Heart Association confirmed its ability to accurately detect AFib, with performance comparable to other smartwatches using photoplethysmography technology. It received FDA 510(k) clearance for an irregular pulse monitor feature, specifically for patients aged 22 and older who have been diagnosed with or are susceptible to AFib.
Heart Failure Risk Prediction
The Verily Study Watch has shown potential in identifying patients at risk for heart failure (HF). A study demonstrated that walking behavior captured by the device is associated with different levels of HF risk for asymptomatic individuals or those at risk of developing HF compared to healthy patients. Digital measures of walking, including cadence and pace, showed significant association with pre-clinical stages of HF.
Cardiac Monitoring Integration
The Study Watch is designed for continuous, non-invasive monitoring of physiological and environmental metrics, including heart rate and electrodermal activity. It has been used in various clinical research programs to collect biometric health information. Verily is also collaborating with iRhythm Technologies to leverage the Study Watch with ECG and Irregular Pulse Monitor and iRhythm's Zio Service for continuous monitoring, data analytics, and cloud-based machine learning to monitor AFib.
AHA/ACC Guideline Alignment
The American Heart Association (AHA) has a stated goal of advancing mobile health to enhance prevention and care, aligning with the Study Watch's focus on cardiovascular health. The device's ECG feature is useful in diagnosing various heart conditions.
Real-Time Alert Capability
If atrial fibrillation is suspected based on photoplethysmography, the Verily Study Watch prompts the wearer to take a single-lead ECG for confirmation. The device has an onboard processor to support real-time algorithms.
Physician Tip
The Verily Study Watch is a clinical-grade, prescription-only device primarily for research and clinical management of atrial fibrillation. It offers continuous monitoring and on-demand ECG capabilities. Physicians should consider its use for long-term AFib surveillance and for collecting real-world data on walking behaviors that may indicate heart failure risk. The data collected can complement in-clinic assessments and potentially aid in earlier identification and management of cardiovascular conditions. It is important to note that the device is not for direct consumer use and results require review by a cardiographic technician before being shared with the physician.
Verily is actively pursuing integrations to enhance the Study Watch's capabilities. A key collaboration is with iRhythm Technologies, aiming to integrate the Study Watch's ECG and Irregular Pulse Monitor with iRhythm's Zio Service for continuous AFib monitoring, data analytics, and cloud-based machine learning. Additionally, Verily has partnered with Samsung to integrate sensor data from Samsung Galaxy Watch into Verily's precision health platform, Pre, to accelerate clinical research and provide advanced insights for study sponsors. This collaboration will allow for the integration of various health measures like heart rate, blood oxygen, and body composition from Galaxy Watches into Verily's data solutions for analysis and modeling.

Frequently Asked Questions
The Verily Study Watch is primarily designed for clinical research to collect real-world data for conditions like cardiovascular health and Parkinson's disease, rather than direct integration into routine clinical practice for individual patient monitoring. Its AI/ML capabilities are used to process and analyze the collected biosensing data, aiming to provide insights into disease progression and daily symptoms for research purposes.
The Verily Study Watch has received FDA 510(k) clearance as a Class II medical device for its on-demand ECG feature and irregular pulse monitor, making it a prescription-only device. All data stored on the watch are encrypted before being uploaded and processed in the cloud, addressing data privacy concerns.
While the Study Watch records and transfers single-channel ECG rhythms, its initial FDA clearance did not include analysis features for detecting atrial fibrillation or normal sinus rhythm on the device itself. Additionally, in some research contexts, it may not accurately measure non-motor symptoms for conditions like Parkinson's disease. Patient compliance with wearing the device can also decrease over time, potentially affecting data continuity.
Unlike many consumer smartwatches, the Verily Study Watch is a prescription-only, clinical-grade device primarily for research, though other smartwatches like Apple Watch and Samsung Galaxy Watch also have FDA-cleared ECG features and irregular rhythm notifications. While consumer wearables are increasingly accurate for heart rate and AFib detection, medical-grade devices like insertable cardiac monitors may offer superior continuous monitoring and detect more AFib episodes, especially nocturnal ones.
The Verily Study Watch is not available for commercial sale to individual consumers or directly to physicians for general clinical use. It is primarily made available to participants in observational studies and clinical trials conducted by Verily and its partners. Therefore, a direct pricing model for physicians to acquire it for routine patient care is not applicable.
For ECG data, the Study Watch records, stores, transfers, and displays single-channel ECG waveforms, which are then sent to the healthcare provider for review. The patient does not have direct access to independently view these data on the device. This indicates that significant clinical interpretation by the physician is still required, as the device itself does not provide diagnostic analysis.
Patients using the Study Watch do not have direct access to independently view their ECG data on the device; this information is recorded and transferred to their healthcare provider. This design choice means the device is intended to augment physician-led care and research, rather than empowering direct patient self-diagnosis or interpretation, which could streamline workflow by reducing false positives seen with consumer devices.
