A case report of a 16-year-old competitive runner experienced sudden-onset tachycardia episodes, exceeding 200 bpm, were 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.

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.

Clinical Validation

This study aimed to validate the Frontier X+ (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+ 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.
