Frontier X Plus vs. Holter Monitor : The Future of AFib Detection at Home

If you’ve ever experienced unexplained palpitations, dizziness, or chest discomfort, your doctor may have recommended a Holter monitor. While this traditional device has helped many detect heart rhythm issues over the years, the future of cardiac care is shifting – and it’s moving right into your home. With the rise in wearable ECG monitoring devices like the Frontier X Plus, you now have the opportunity to take control of your heart health like never before. Here, we’ll explore how Frontier X Plus compares to Holter monitors and why ECG monitoring at home is quickly becoming the new standard in cardiac care.

A Quick Look at Holter Monitors

Holter monitors are portable ECG devices that continuously record your heart’s electrical activity over a period of 24 to 48 hours. Worn around your neck or waist with electrodes stuck to your chest, Holter monitors collect data for your physician to analyze after the device is returned.

They remain widely used — in fact, the U.S. cardiac Holter monitor market was valued at approximately USD 164.6 million in 2024 and is projected to reach USD 229.1 million by 2033, according to IMARC Group. This steady growth reflects ongoing demand, but also highlights opportunities for innovation in ambulatory ECG monitoring.

While Holters have been essential in diagnosing arrhythmias and silent heart conditions, they have limitations, especially when it comes to comfort, real-time feedback, and prolonged use.

Meet The Frontier X Plus — The Modern Alternative

Frontier X Plus is a chest-worn, FDA-510(k) cleared, prescription-based ECG monitor designed for remote heart monitoring in real-world environments. Whether you’re at rest, walking, working, or even exercising, it continuously tracks your heart rhythms throughout the day. With a quick recharge time of about an hour, you can wear the device day after day, for as long as your doctor prescribes, syncing your ECG data to the cloud each night. This enables seamless, uninterrupted multi-day monitoring – ideal for capturing intermittent symptoms and maintaining a complete view of your heart health over time.

Unlike Holters, which are typically worn once and reviewed later, Frontier X Plus allows your clinician to monitor your heart in the moment and take timely action when needed. It’s lightweight, wireless, and comfortable, making it perfect for ECG monitoring at home.

Real-Time Insight vs. Retrospective Review

With a Holter monitor, you wear the device for a day or two, return it, and then wait for your doctor to analyze the data. If your abnormal heartbeat didn’t occur during that window, it might be missed entirely.

With Frontier X Plus, you’re not stuck waiting. The device syncs ECG data through a companion app and uploads it to a secure clinician dashboard. If you’re enrolled in a monitoring program, your data is reviewed daily. Alerts are triggered if you haven’t synced in over 36 hours or if data quality is low, ensuring continuous, actionable monitoring.

This is one step towards innovation and a giant leap forward in care. If you suffer from intermittent Atrial Fibrillation, Tachycardia, and Bradycardia, real-time detection can be the difference between proactive care and a missed diagnosis.

Comfort and Ease of Use

Holter monitors require multiple sticky electrodes, wires, and sometimes a belt or pouch. You may be told not to shower, and movement can be limited. If you’ve worn one, you know it’s not ideal for long-term monitoring or active lifestyles.

Frontier X Plus? It’s built for modern living. You strap it onto your chest like a fitness tracker. There are no wires. No gels. No bulky external units. You charge it like your phone, sync it through your app, and go about your day.

You can even livestream your ECG during setup to make sure you’re getting a clean signal — something that Holter monitors can’t do.

Designed for the Way You Live

Think about it: would you rather strap on a device that restricts your movement for 24 hours, or wear something designed to be barely noticeable as you go about your daily routine?

Frontier X Plus is built with home heart monitoring in mind. It’s water-resistant, comfortable under clothing, and doesn’t interfere with sleep or exercise. Whether you’re managing a known heart condition or just monitoring your heart’s behavior during endurance training, this device fits into your lifestyle seamlessly.

Clinical Accuracy You Can Trust

You might be wondering, “Is it as accurate as a Holter?” The answer is yes — and in many ways, even better.

Frontier X Plus uses FDA-cleared algorithms to detect various cardiac rhythms, including:

• Normal Sinus Rhythm
• Atrial Fibrillation
• Tachycardia (fast heart rate)
• Bradycardia (slow heart rate)

In clinical validation studies, the device demonstrated sensitivity and specificity comparable to traditional 12-lead ECGs.

End-of-Study Reports for Your Doctor

Once your monitoring period ends (typically 2 days), a certified cardiac physiologist or your prescribing clinician generates a full report from your ECG data. This includes breakdowns of heart rhythms, flags for abnormalities, and trend analysis.

You or your doctor receives this report within 24 hours, either via secure email or directly uploaded into your healthcare provider’s EMR system (e.g., EPIC).

This speed and depth of feedback simply isn’t available with legacy Holter workflows.

When Should You Ask About Frontier X Plus?

If you’re experiencing symptoms like:

• Fluttering or skipped beats
• Unexplained fatigue
• Shortness of breath
• Fainting spells or dizziness
• Irregular pulse or chest discomfort

…talk to your physician about ambulatory ECG monitoring. Ask whether a remote heart monitoring option like Frontier X Plus might be more appropriate than a Holter monitor.

It’s especially useful if your symptoms are intermittent or occur during specific activities like sleep or exercise. With a real-time system, your clinician won’t have to guess what’s happening when you’re not in the clinic.

The Future Is on Your Chest

Holter monitors had their moment. They’re still useful in many settings. But for today’s patients — whether you’re active, managing a heart condition, or simply looking for peace of mind — Frontier X Plus represents a smarter, more responsive path forward.

The ability to monitor your heart from home, share data instantly with your doctor, and wear a device that’s truly built for your lifestyle is what makes this wearable a leader in its category.

Ask your physician about Frontier X Plus today — because the future of heart monitoring is here, and it’s wearable.
