Clinical Validation

This study aimed to validate the Frontier X Plus (FX+) single-lead, continuous ECG device by comparing its performance against the traditional FDA Cleared 12-lead ECG in ​832 patients​ in both a clinical and real world setting including individuals with and without atrial fibrillation (AFib). The performance of the Frontier X Plus in detecting atrial fibrillation (AF) demonstrated a sensitivity of 98.10% and a specificity of ​97.88%, when compared to the paired gold standard device as adjudicated by 3 independent cardiologists.

Wearables as an Aid to Cardiovascular Diagnosis in a Young Runner

Roberts, William O. MD, MS, FACSM1; Levine, Benjamin D. MD, FACSM2

A case report of a 16-year-old competitive runner experiencing sudden-onset tachycardia episodes, exceeding 200 bpm, documented using a Garmin Instinct™ watch. Despite normal cardiac evaluations, the patient later used a Frontier X™ ECG Fitness Tracker, which successfully captured heart rhythm data during episodes and helped monitor his response to beta blocker therapy.

Safety, Feasibility, and Effectiveness of the Remotely Delivered Pulmonary Hypertension and Home-Based (PHAHB) Physical Activity Intervention

Ciara McCormack, Brona Kehoe, Sarah Cullivan, Noel McCaffrey, Sean Gaine, Brian McCullagh, Andrew McCarren, Sarah J Hardcastle, Niall M Moyna

The Frontier X device played a crucial role in continuously monitoring heart rate and respiratory rate, ensuring safety and enabling real-time feedback during the exercise sessions. The success of this remotely delivered intervention suggests that similar models could be effectively implemented for broader PH patient populations, offering a scalable alternative to hospital-based programs.

FAQ’s

What is Frontier X Plus?

Frontier X Plus™ by Fourth Frontier® is a wearable ambulatory electrocardiogram (EKG or ECG) recorder and display product affixed to the chest strap, a companion mobile application, and a web application for analysis of ECG. It is a novel, self-applied continuous ambulatory ECG solution for arrhythmia detection and management.

The Frontier X Plus system also displays ECG waveform and ECG rhythm analysis; detecting the presence of normal sinus rhythm, atrial fibrillation, bradycardia, tachycardia, and inconclusive and unreadable rhythms. The device is intended for use by healthcare professionals, patients with known or suspected heart conditions and health-conscious individuals. It is indicated for use on adult patients who may be asymptomatic or who may suffer from transient symptoms requiring cardiac monitoring. This chest heart rate monitor is a non-invasive, lightweight, rechargeable battery- operated wireless ambulatory ECG monitor.
