Abstract 14561: The Role of Symptoms in Adherence to mHealth ECG Monitoring for Atrial Fibrillation

Introduction: Mobile health (mHealth) ECG technology via a smartphone can capture a real time ECG recording and accurately document AF. However, AF is often asymptomatic or individuals may not be able to distinguish symptoms due to AF from other underlying etiologies. Adherence to mHealth is variable and reasons for non-adherence are poorly understood. The aim of this study was to investigate adherence to mHealth ECG monitoring among patients with a prior history of AF. Methods: A pilot cohort from within the larger ongoing NIH randomized trial; iPhone Helping Evaluate Atrial Arrhythmias through Technology (iHEART) was evaluated to determine differences in mHealth use and the association with symptoms over a 6-month follow-up period. We examined 50 adults who were utilizing the AliveCor™ mHealth ECG monitor and application. Adherence rates and reasons for failing to transmit were captured. Results: Fifty two percent of iHEART subjects (76% male, mean age 55 +/- 10 years) required frequent reminders (> 3) ...
