Noninvasive Detection of Left-Ventricular Systolic Dysfunction by Acoustic Cardiography in Atrial Fibrillation
Figure 2
Receiver-operating characteristic (ROC) curves are presented for electromechanical activation time, the systolic dysfunction index and ejection fraction for populations with (red curve) and without atrial fibrillation (blue curve). Afib: atrial fibrillation.
