Smartphone ECGs as Accurate as Standard
accuracy was equivalent between smartphone and standard ECGs for detecting atrial rate and rhythm, atrioventricular block, and QRS delay.
(HealthDay News) -- Smartphone electrocardiogram (ECG) accurately detects baseline intervals, atrial rate, and rhythm, according to a study published in the Journal of Cardiovascular Electrophysiology.
Zachary C. Haberman, from the University of Southern California in Los Angeles, and colleagues compared the accuracy of standard 12-lead ECG to the wireless, single-lead smartphone ECG in healthy young adults, elite athletes, and cardiology clinic patients. Automated algorithms interpreted the de-identified ECGs, which were then adjudicated by 2 board-certified electrophysiologists.
The researchers found that accuracy was equivalent between smartphone and standard ECGs for detecting atrial rate and rhythm, atrioventricular block, and QRS delay. Specificities were all above 94% for both ECG methods, while sensitivities ranged from 72% (QRS delay) to 94% (atrial fibrillation).
"Efficient ECG analysis using automated discrimination and an enhanced smartphone application with notification capabilities are features that can be easily incorporated into the acquisition process," the authors write.
