About

In this study the ability of smartphone sensors (accelerometer and gyroscope) to identify patients with heart failure will be studied.

Full description

Heart Failure (HF) is a condition where heart is unable to maintain adequate volume of blood in circulation corresponding to prevailing physiological demand. Gyrocardiography is a technique that utilizes micro electromechanical sensors (MEMS), accelerometer and gyroscope, to detect vibrations and rotation of thorax caused by cardiac motion. The main purpose of this study is to test the ability of an app of a smartphone with embedded motion sensors, positioned on the chest which measures the movements and function of the heart, to identify patients with different types of heart failure and their characteristics, as compared with clinical diagnosis. Echocardiography will also be used to confirm changes in cardiac cardiac mechanics including strain, cardiac torsion, diastolic filling characteristics.
