Heart Failure (HF) is a syndrome where the heart is unable to pump or fill adequately to meet the circulatory needs of the body. The main purpose of this study is to test the ability a novel wearable sensor based on a smartphone app (Precordior CardioSignal app) in combination with a sensor device (Suunto Movesense sensor) to non-invasively measure cardiac motion and function. The phone and sensor are positioned on the chest and echocardiography is used as a gold standard to assess cardiac mechanics including myocardial strain, cardiac torsion, diastolic filling characteristics, hemodynamics including pressure estimates and stroke volume.
The study will test the ability a novel wearable sensor based on a smartphone app (Precordior CardioSignal app) in combination with a sensor device (Suunto Movesense sensor) to non-invasively measure cardiac motion and function.
