MyoVista wavECG Clinical Evaluation: >=60 y/o Enrichment Population

The study has a planned enrollment of at least 50 subjects to obtain approximately 40 subjects with a "normal" septal and lateral e' value on echocardiogram. The criteria defined as septal e'\< 7 cm/s or lateral e'\< 10 cm/s for relaxation abnormality based on ASE/AECVI guidelines will be used for the evaluation of LV diastolic function which is associated with abnormal relaxation in echocardiography. An independent Core Lab will verify all septal and lateral e' values on the site-acquired echocardiograms and these Core Lab measurements will serve as the ground truth standard with regard to the presence of LV relaxation abnormalities. Analysis of data from a prior multi-center study has revealed good correlation between the MyoVista wavECG results and echocardiography for the presence of LV relaxation abnormalities. This current study (HS-CLINVAL-002) is intended to supplement data collected in prior and ongoing studies, namely HS-CLINVAL-001, by recruiting individuals who are \>60 years old and who are anticipated to have normal echocardiogram results based on a screening of selected clinical characteristics. Subjects in this study will be invited to participate and receive non-standard-of-care echocardiograms and a study driven MyoVista test. The study will continue to focus on LV relaxation abnormalities by gathering additional device validation data for the purposes of regulatory approval peer-reviewed publications. Echocardiograms of study subjects will be used to compare/validate the study findings.
