Fibricheck detection capabilities for atrial fibrillation (FDA-AF): a multicenter validation study
The Fibricheck FDA-AF study validates the FibriCheck platform as a highly accurate and reliable tool for detecting Atrial Fibrillation (AF) in a diverse patient population. Demonstrating consistent performance across ten common smartphone devices, the study highlights its ease of implementation and potential as a resource-efficient method for AF detection and monitoring outside of clinical settings. The platform achieves 98.5% accuracy, 96.3% sensitivity, and 99.3% specificity, even with varying skin tones and BMI, especially when technician verification is applied, making it superior to or equivalent to other FDA-cleared devices.

Mitigating Skin Tone and BMI Impact
The study found that sensitivity of FibriCheck was reduced in individuals with darker skin tones (Fitzpatrick types V and VI) and higher BMIs (≥30). However, this challenge was successfully mitigated by the implementation of FibriCheck technician verification. With verification, sensitivity for dark skin tones improved from 79.6% to 93.8% and for higher BMI improved from 93.7% to 98.8%. This highlights the platform's robust design and ability to overcome common physiological barriers through combined AI and human oversight.

Phased Implementation Roadmap
A strategic approach to integrating AI-powered AF detection into your clinical workflow.
Phase 1: Pilot & Validation
Identify a pilot group of patients and clinicians. Integrate FibriCheck into existing workflows. Collect initial data and conduct internal validation against 12-lead ECG. Gather feedback from clinicians on usability and efficiency.
Phase 2: Scaled Deployment
Based on pilot success, expand FibriCheck deployment to a larger patient cohort. Develop standardized training for all clinical staff. Establish clear protocols for technician verification and data review. Monitor performance metrics and patient outcomes.
Phase 3: Integration & Optimization
Integrate FibriCheck data with existing Electronic Health Records (EHR) systems. Continuously optimize AI algorithms based on real-world data and clinical feedback. Explore opportunities for preventative care and proactive patient management derived from FibriCheck insights.
