Repeatability and Reproducibility of the CADence™System (SEQUEL)
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
The CADence™ system is comprised of a digital stethoscope used to record cardiac (heart) sounds, with integrated sensor used to record electrical activity of the heart (ECG), a single-use patient booklet, and the CADence™ Software application. CADence™ Software is a clinical decision support tool for the noninvasive functional evaluation of patients presenting with chest pain and at least two coronary artery disease risk factors that is intended to aid a qualified clinician's analysis of normal/physiological and pathological heart murmurs and in ruling out significant coronary disease as a cause for these symptoms of cardiovascular disease, utilizing simultaneous recording of cardiac sounds and ECG.
The purpose of this study is to assess the precision of the CADence site using multiple operators, cadence systems and clinical sites.
