Nonlinear Time Domain Relation between Respiratory Phase and Timing of the First Heart Sound
The previous studies on respiratory physiology have indicated that inspiration and expiration have opposite effects on heart hemodynamics. The basic reason why these opposite hemodynamic changes cause regular timing variations in heart sounds is the heart sound generation mechanism that the acoustic...
