Comparison of HRV indices obtained from ECG and SCG signals from CEBS database

BioMedical Engineering OnLine, 2019
Background Heart rate variability (HRV) has become a useful tool of assessing the function of the heart and of the autonomic nervous system. Over the recent years, there has been interest in heart rate monitoring without electrodes.

Seismocardiography - a non-invasive method of assessing systolic and diastolic left ventricular function in ischaemic heart disease [PDF]

, 2006
Background: Seismocardiography (SCG) is a new non-invasive method which can assess left ventricular function (LVF) during exercise testing based on cardiac time intervals (CTI). There are no data assessing cardiac time intervals during exercise ischaemia
