Three groups of subjects were studied by means of noninvasive diagnostic tracings. 50 patients, aged 43 to 94 yr, with an innocent aortic systolic murmur; 50 patients, aged 7 to 86 yr, with the systolic murmur of aortic stenosis; and 50 normal subjects (controls) aged 9 to 81 yr. The important differential criteria were listed in two groups: the phonocardiographic amplitude of the second sound and the characteristics of the murmur; and the various parameters of the arterial pulse. The differences between the various groups were statistically significant and were further confirmed by clinical and laboratory data.

Abstract
Three groups of subjects were studied by means of noninvasive diagnostic tracings. 50 patients, aged 43 to 94 yr, with an innocent aortic systolic murmur; 50 patients, aged 7 to 86 yr, with the systolic murmur of aortic stenosis; and 50 normal subjects (controls) aged 9 to 81 yr. The important differential criteria were listed in two groups: the phonocardiographic amplitude of the second sound and the characteristics of the murmur; and the various parameters of the arterial pulse. The differences between the various groups were statistically significant and were further confirmed by clinical and laboratory data.File in questo prodotto:
