Monitoring Asymptomatic Atrial Fibrillation With The Frontier X Plus

Atrial Fibrillation (AF) is the most common type of arrhythmia affecting millions globally, yet it often goes unnoticed. More than 59 million individuals lived with AF in 2019. Many people live with what’s called asymptomatic AF or silent AF, where irregular heart rhythms occur without any obvious symptoms. While the absence of symptoms might seem like a relief to you, if left unchecked, silent AF raises the risk of serious complications like stroke.  That’s where the Frontier X Plus, a patchless continuous ECG monitoring device, comes to your rescue.

Moreover, after your cardiac procedure, monitoring for silent or asymptomatic AF becomes especially important. These irregular heart rhythms, which often occur without symptoms, can significantly increase the risk of stroke if left undetected. Continuous, clinical-grade ECG monitoring with devices like the Frontier X Plus ensures that these hidden episodes are caught early, enabling timely medical intervention during this critical recovery phase.

In this blog, you will explore how the Frontier X Plus enables you and your clinician to detect and manage silent AFs through continuous, real-time, remote heart monitoring — all while you go about your daily routine.

What Is Asymptomatic Atrial Fibrillation/Silent AF?

Asymptomatic AF is when you experience episodes of Atrial Fibrillation without feeling any noticeable symptoms. Unlike typical AF, which can cause palpitations, fatigue, or dizziness, asymptomatic AF may occur silently for months or even years. Yet, it poses the same elevated risks of blood clots, stroke, and heart failure.

According to studies, nearly 27% of AF cases are asymptomatic, and undetected AF is responsible for up to one-third of all strokes. That’s why routine ECG monitoring at home — with a clinically validated device like Frontier X Plus — is essential.

Why Traditional Monitoring Often Falls Short

Standard devices, such as Holter monitors and smartwatches, are not designed to detect intermittent or silent episodes. Holters usually record for only 24–48 hours, which may miss an AFib event entirely, and their bulky design with adhesive electrodes and wires often causes skin irritation and disrupts sleep. Smartwatches, while convenient, rely on short, 30 to 60-second user-initiated ECG recordings and frequently deliver inconclusive or inaccurate results due to poor signal quality or motion. Their wrist-based placement can also lead to signal interruptions during daily movement, reducing reliability for clinical use.

When you’re not feeling symptoms, you likely won’t think of initiating a recording, which is exactly why Frontier X Plus is different.

The Frontier X Plus: Always-On ECG Monitoring at Home

The Frontier X Plus is an FDA 510(k)-cleared, chest-worn, patchless ECG monitor that captures your heart’s electrical activity continuously throughout the day — even when you’re not aware of anything unusual.

Key features include:

• Continuous ECG monitoring for up to 23 hours per hour of charge, as long as your clinician prescribes, serving as an extended Holter
• Real-time and retrospective ECG data review – Your heart data can be checked both as it’s happening and after the recording is done
• Secure cloud storage accessible by your clinician – Your heart recordings are safely stored online, so your doctor can review them anytime
• Symptom tagging and activity labeling for context – You can note how you’re feeling and what you’re doing during recordings, so your doctor gets the full picture

This makes it ideal for catching asymptomatic AF that may otherwise be missed by short-term or user-activated devices.

Monitoring That Blends Into Your Lifestyle

You don’t need to visit a clinic or stay wired to bulky equipment to take an ECG. With the Frontier X Plus, you simply wear a lightweight, patchless device on your chest using a soft strap. It syncs effortlessly to a companion mobile app, where your data is uploaded to a secure dashboard.

You can go about your routine — working, exercising, sleeping, driving, riding — while your device handles the heart hustle behind the scenes. If something concerning is detected, your physician can review the data and intervene early.

Clinically Actionable Data That Doctors Trust

The Frontier X Plus isn’t just a wellness gadget — it’s a prescription-based tool used in cardiac rehab, remote patient monitoring, and arrhythmia diagnostics. Its advanced algorithms detect:

• Atrial Fibrillation

• Bradycardia

• Tachycardia

• Normal sinus rhythm

At the end of your monitoring period, your doctor receives a detailed report outlining heart rate trends, rhythm breakdowns, and any arrhythmic episodes, giving them the insight they need to make informed treatment decisions.

Peace of Mind Without the Guesswork

Living with asymptomatic AF can feel like living in the dark. The Frontier X Plus shines a light on your heart’s rhythm — even when you don’t feel a thing. Whether you’re being screened for AF due to family history, managing an existing condition, or recovering from a cardiac procedure, this device offers the clarity and confidence you deserve.

Final Thoughts

If you’re at risk of silent arrhythmias like asymptomatic AF, don’t wait for symptoms to appear. With the Frontier X Plus, you get continuous, clinical-grade ECG monitoring — all from the comfort of your own place. Unlike smartwatches or Holters, the Frontier X Plus gives you and your care team the full picture, helping detect AF early and intervene sooner.
