Frontier X Plus: The Best Ambulatory ECG Monitor for AFib Detection

Why Timely ECG Monitoring is Critical for Your Heart Health

Heart conditions can develop silently and escalate without warning. For individuals managing known cardiac issues or those experiencing unexplained symptoms like palpitations or fatigue, ongoing rhythm monitoring can be life-changing. But staying connected to your heart shouldn’t mean staying confined to a clinic. That’s where the Frontier X Plus comes in — a compact, ambulatory ECG monitor that travels with you, capturing critical cardiac insights whether you’re working, exercising, or simply going about your day. With real-time AFib detection and continuous ECG monitoring, it helps identify arrhythmias as they happen, so you and your physician can act before symptoms worsen.

What Is the Frontier X Plus?

The Frontier X Plus is an FDA 510(k) cleared, prescription-based, wearable ECG monitor designed for ambulatory cardiac monitoring in real-life settings. This lightweight, patchless ECG device is worn on the chest using a comfortable strap and captures continuous ECG data for up to 24 hours on a single charge.

Unlike traditional Holter monitors, the Frontier X Plus allows you and your clinician to monitor heart rhythms in real time or retrospectively, with easy access to your ECG data via a mobile app and web dashboard. It has been clinically validated and shown to have comparable arrhythmia detection accuracy to standard 12-lead ECGs, making it highly reliable for medical use.

Why Frontier X Plus is the Best Ambulatory ECG Monitor

1. Continuous, Real-Time ECG Monitoring

    Unlike traditional Holter monitors or even other telemetry devices that offer retrospective reviews or limited monitoring windows, the Frontier X Plus empowers you to capture your heart rhythm 24/7, in real time, for as many days as clinically required — all with just one hour of charging per day. Whether you’re walking, working, or sleeping, this device records your ECG data without interrupting your routine. This makes it ideal for detecting transient symptoms like dizziness, palpitations, fatigue, and even silent atrial fibrillation (AF).

2. Remote Review and Clinical Oversight

   The Frontier X Plus supports remote ECG data review by securely syncing recordings to a cloud-based clinician dashboard. Throughout the monitoring period, clinicians can log in to assess the patient’s ECG data on a daily basis, evaluating signal quality and identifying abnormal heart rhythms such as AFib, bradycardia, or tachycardia. This remote access ensures timely clinical oversight, allowing physicians to track progression, correlate symptoms, and make informed decisions — all without requiring the patient to return to the clinic. 

3. Precise Detection of Atrial Fibrillation and Other Arrhythmias

   The device uses advanced algorithms that analyze 20-second ECG segments to identify and classify rhythms. These include normal sinus rhythm, bradycardia, tachycardia, and atrial fibrillation. If the signal quality is compromised, it is marked as ‘unreadable’ to ensure clinical accuracy is maintained.

4. Patient-Friendly Design and Workflow

   Frontier X Plus is a self-applied, patchless ECG monitor you can wear comfortably throughout the day — no wires, no adhesives, no clinic visits. Unlike Holter monitors, it’s lighter, easier to use, and convenient for real-world monitoring. Whether you’re managing your heart health independently or participating in a cardiac rehab program, the device fits into your lifestyle without disruption. The companion app helps you set up in minutes, tag symptoms, and label activities like sleep or exercise for clearer clinical insights.

5. End-of-Study Reports for Clinical Decision Making.

   At the end of the prescribed monitoring period, you get a detailed ECG report. This includes rhythm breakdowns, arrhythmia flags, and heart rate trends – all of which aid your physicians in diagnosing or ruling out cardiac conditions like AF.

The Frontier X Plus stands out among ambulatory ECG monitors by offering continuous, real-time monitoring for up to 24 hours on a single charge. This capability is unparalleled among current devices, making it a superior choice for both patients and clinicians seeking reliable, long-duration cardiac monitoring. Here’s a comparison table summarizing how Frontier X Plus stands out against other commonly used ambulatory ECG monitoring devices

Key Use Cases for The Frontier X Plus

• Post-surgical cardiac monitoring
• Evaluating unexplained symptoms like syncope or palpitations
• Monitoring known heart conditions such as atrial fibrillation
• Sports cardiology and endurance athletes
• Preventive heart health assessments
• Alternative to Holter monitoring 
• Better cardiac rehab compliance 

Clinically Validated Performance

The Frontier X Plus has been validated through both bench testing and clinical investigations involving over 800 patients across diverse demographics. The device demonstrated high sensitivity and specificity in detecting all major arrhythmias. Importantly, its performance in detecting AF, bradycardia, and tachycardia was consistent with standard 12-lead ECGs, making it a trustworthy tool for remote monitoring.

Final Thoughts

If you’re a healthcare provider looking to offer your patients the best in at-home heart monitoring or an individual looking for a reliable ECG monitoring at home solution, the Frontier X Plus stands out for its clinical-grade accuracy, ease of use, and seamless integration into daily life. It’s not just a home heart monitor – it’s a bridge between everyday living and professional cardiac oversight.
