Tempus ECG-AF vs Merlin.net
AI Verdict
Choose Tempus ECG-AF if…
Choose Tempus ECG-AF if your primary objective is to proactively identify patients aged 65 or older who are at an increased risk of developing new-onset atrial fibrillation within the next 12 months, utilizing standard 12-lead ECG recordings. This tool is ideal for screening efforts in a geriatric population without pre-existing AF or implanted cardiac devices, facilitating earlier risk stratification and potential intervention.

Head-to-Head
AI-generated assessment across six dimensions based on each tool's documented features and compliance posture. Grounded in public data — not a substitute for hands-on evaluation.
Usability
Merlin.netMerlin.net offers a comprehensive web-based platform with a dedicated user interface, featuring tools like DirectAlerts, SmartSchedule, and DirectCall for active clinician interaction and remote patient management. In contrast, Tempus ECG-AF is an algorithm that integrates into existing healthcare facility systems and explicitly states it does not have a dedicated user interface, meaning its output is consumed within other systems rather than through its own direct clinician-facing application.
Clinical Value
Tempus ECG-AFTempus ECG-AF provides a unique clinical value by utilizing AI to predict the risk of new-onset atrial fibrillation within 12 months from standard 12-lead ECGs, enabling earlier identification and follow-up for a broad patient population. Merlin.net, while valuable, focuses on the remote management and monitoring of patients already diagnosed and implanted with cardiac devices.
Pricing & Value
Tempus ECG-AFWhile both tools require contacting the vendor for pricing, Tempus ECG-AF transparently provides specific CMS reimbursement CPT codes (0764T and 0765T) and a Medicare rate of $128.90, effective January 1, 2025. This explicit information on reimbursement pathways significantly enhances its perceived value by offering clarity on financial sustainability for healthcare providers.
Enterprise Readiness
Merlin.netBoth tools are FDA-cleared, HIPAA compliant, and offer BAAs. However, Merlin.net demonstrates stronger enterprise readiness through its cloud-based deployment on Microsoft Azure with EU regionalized data processing and explicit support for seamless EHR integration via HL7 standards. Tempus ECG-AF integrates with existing ECG platforms and EHRs, but Merlin.net's detailed cloud infrastructure and specific integration standards suggest a more robust and scalable solution for large healthcare systems.
Innovation
Tempus ECG-AFTempus ECG-AF represents a more significant innovation by applying AI to standard ECGs for predictive risk assessment of future atrial fibrillation onset, a novel approach to proactive disease identification. Merlin.net, while a comprehensive remote monitoring platform with advanced features, operates within the more established domain of managing patients with existing implanted cardiac devices.
Support & Docs
Merlin.netMerlin.net offers extensive support resources, including a detailed 'Merlin.net Patient Care Network Arrhythmia and Device Management Application Help Manual' and an 'EHRDirectu2122 Integration FAQ,' alongside multiple customer support contact numbers. Tempus ECG-AF provides a contact email and phone number for support but does not detail the availability of comprehensive documentation or user resources.
