| The most important study variables are: Stroke volume(SV): the amount of blood leaving the heart with a single heartbeat. Pre Ejection Period (PEP); The time between the onset of the electrical activation of the ventricles and the mechanical activation of the ventricles (opening of the aortic valve). This is a measure of sympathetic activity and contractility of the heart muscle. Respiratory sinus arrhythmia (RSA); this is a naturally occurring variation in heart frequency during a breathing cycle.
