Overview

The Verily Study Watch is a sensor-based wearable device designed for non-invasive, continuous physiological monitoring, primarily utilized in clinical research and observational studies. It is a prescription-only device. The watch features multiple physiological sensors capable of collecting biometric health information, including electrocardiogram (ECG), heart rate, electrodermal activity, and inertial movements. Data captured by the Study Watch is encrypted before being uploaded and processed in Verily’s secure cloud platform, leveraging proprietary algorithms and machine learning tools for analysis. Engineered for long-term data collection with minimal interruption, it boasts a battery life of up to one week and incorporates an e-ink display for power efficiency. The device is intended for use by healthcare professionals and adult patients (22 years or older) with known or suspected heart conditions, as well as health-conscious individuals participating in research.

What Physicians Need to Know

ECG/EKG Analysis Capability
The Verily Study Watch has received FDA 510(k) clearance for its on-demand ECG feature, enabling it to record, store, transfer, and display single-channel ECG rhythms. It utilizes two dedicated sensing electrodes for ECG measurement. The collected ECG data is securely transferred to a cloud server for review by healthcare professionals via a web portal, rather than being directly accessible to the patient.
Arrhythmia Detection Accuracy
The Study Watch, with its Irregular Pulse Monitor feature, is designed for continuous monitoring and detection of atrial fibrillation (AFib) using photoplethysmography (PPG) and prompts for a confirmatory single-lead ECG if AFib is suspected. Clinical studies have confirmed its accuracy in detecting AFib episodes, demonstrating an interval-level sensitivity of 96.1% and specificity of 98.1% for AF detection with its PPG-based algorithm.
Heart Failure Risk Prediction
Recent research indicates the Verily Study Watch's potential in identifying patients at risk for heart failure. A study utilizing digital walking measures captured by the watch found significant associations with varying levels of heart failure risk in asymptomatic individuals or those predisposed to the condition, with these measures correlating with in-clinic physical functioning tests.
Cardiac Monitoring Integration
The Study Watch is a prescription-only device intended for unobtrusive biosensing and continuous physiological data collection in clinical research, including heart rate and ECG. Data is securely uploaded and processed in the cloud using Verily's backend algorithms and machine learning tools, accessible to healthcare providers via a web portal. It integrates with iRhythm's Zio Service for enhanced continuous AFib monitoring, data analytics, and cloud-based machine learning.
AHA/ACC Guideline Alignment
While Verily's focus on cardiovascular health aligns with the American Heart Association's (AHA) goal of advancing mobile health for prevention and care, the Study Watch's primary role is as an FDA-cleared device for ECG recording and irregular pulse monitoring in clinical research settings, supporting data collection for clinicians.
Real-Time Alert Capability
The device features a real-time alert system that prompts the wearer to take a single-lead ECG if its photoplethysmography (PPG) readings suggest atrial fibrillation. The results are then analyzed by a cardiographic technician before being shared with the patient's physician.
Physician Tip

The Verily Study Watch is a prescription-only, clinical-grade wearable primarily designed for research and long-term physiological data collection. Physicians should leverage its FDA-cleared single-channel ECG and irregular pulse (AFib) detection capabilities for monitoring patients with known or suspected heart conditions. The device's ability to capture continuous data, including digital walking measures, can provide valuable insights for heart failure risk stratification and complement traditional in-clinic assessments. Emphasize that raw ECG data is for HCP review via a secure portal, not direct patient interpretation, ensuring clinical oversight.

The Verily Study Watch integrates with Verily's secure cloud-based platform for data transfer and processing, utilizing backend algorithms and machine learning. A key integration is with iRhythm Technologies' Zio Service, which provides continuous AFib monitoring, advanced data analytics, and AI-based arrhythmia diagnosis, aiming to streamline screening, diagnosis, and management of AFib. This collaborative approach enhances the clinical utility of the collected data.

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.
