Diagnostyka elektrokardiograficzna w warunkach SOR za pomocą mobilnego jednoodprowadzeniowego urządzenia EKG

Introduction. Electrocardiography (ECG) is one of the basic diagnostic tests used in emergency departments and by emergency medical services. Life-threatening arrhythmias can be detected using a single-lead ECG. Therefore, single- -lead ECG devices can be used for arrhythmia detection, as their availability steadily increases. Kardia Mobile from Alive- Cor is an example of such a device, recording a single-lead ECG and automatically detecting atrial fibrillation (AF) — the most common complex supraventricular tachyarrhythmia. The aim of our study was to evaluate the utility of a single-lead mobile ECG device in detecting AF in medical practice of emergency services. Material and methods. Study included 118 patients (62 women and 56 men) who were hospitalized in a hospital emergency department and consented to examination with Kardia Mobile immediately after a standard 12-lead ECG. Results of both tests were subsequently compared. Ultimately, 121 different pairs of ECG recordings were analyzed (in 3 cases an additional ECG recording was performed after an electrical cardioversion). Results. Sinus rhythm was identified in 99 patients and 22 were diagnosed with AF using a 12-lead ECG (reference). Kardia Mobile correctly detected AF in 19 of 22 patients with AF (sensitivity: 86.4%) and absence of AF in 96 of 99 people without AF (specificity: 97%). Conclusions. Kardia Mobile device is effective in automated detection of AF among patients hospitalized in the emergency department.
