The significance of left ventricular ejection time in heart failure with reduced ejection fraction
AS Alhakak, JR Teerlink, J Lindenfeld… - European journal of …, 2021 - Wiley Online Library
Left ventricular ejection time (LVET) is defined as the time interval from aortic valve opening

Gravitational dose‐response curves for acute cardiovascular hemodynamics and autonomic responses in a tilt paradigm
Background The cardiovascular system is strongly dependent on the gravitational
environment. Gravitational changes cause mechanical fluid shifts and, in turn, autonomic …

Support vector machine-based classification of vasovagal syncope using head-up tilt test
Simple Summary Syncope is a medical condition triggered by short-lived interruption of the
oxygen supply to the brain, which may result in free fall or accidents. The diagnosis of …
