متن کاملMechanisms of fixed splitting of the second heart sound.
P ROPER elinical anialysis of the secondll heart sound has oily recently been emphasized.1 An ullderstalldill(r of the normal second heart sound has increased the diagnoslie usefulness of its variations in congenital and acquired heart disease. In atrial septal (lefeet, as emphasized by Wood,( the aortic aid pulmnonic coniponelits of the second heart sou]d(l are not o0ly widely separated, but t...
متن کاملSplitting of second heart sound in ventricular ectopic beats.
Doubt has frequently been expressed as to whether electrical asynchrony of the ventricles (e.g. right or left bundle-branch block, right or left ventricular ectopics) causes an equivalent mechanical counterpart. Samet et al. (1959b), using intraventricular pressure records, found evidence of mechanical asynchrony in only 28 per cent of ventricular extrasystoles. The two components of the second...
متن کاملPhysiologic splitting of the second heart sound.
AN INCREASE in the magnitude of splitting of the 2 components of the second heart sound, as heard in the pulmonary area during inspiration, has been recognized for nearly a century.1 Recent reports2' 3 suggest that this phenomenon is due to a relative delay of pulmonary valve closure when the increased venous return during inspiration causes prolongation of right ventricular meehanical systole....
