The application of novel digital intelligent device in the assessment of cardiac function in patients with arrhythmia

Abstract

Acoustic electrocardiography (ACG) is a new non-invasive test that combines the visualization of traditional ECG waveforms and heart-generated sound waveforms to jointly assess cardiac function and cardiac pathology. However, traditional ACG equipment is limited by technology and suffers from problems such as inconvenience and inaccuracy. In recent years, with the development of artificial intelligence technology, some newly developed wearable single-lead ACG devices have appeared, which have applications in the fields of heart failure and coronary heart disease. In order to further clarify the efficacy of this new ACG device for cardiac function assessment in irregular ECG and heart sound waveforms, this study will be validated in patients with arrhythmia, ROC curves show better evaluation of EMAT and EMAT% for HFrEF.
