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 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.

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.

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.
