Murmur alternans in aortic stenosis.
Acquired aortic stenosis, when severe, often gives rise to pulsus alternans.' Other relatively common causes for pulsus alternans include hypertensive heart disease, coronary artery disease, syphilitic heart disease and cardi~myopathy.~ When pulsus alternans is present, the clinician can usually appreciate it through the use of a sphygmomanometer, in which case when the cuff is infiated to near...
متن کاملThe aortic systolic murmur developing with increasing age.
For a number of years increasing attention has been paid to the evaluation of systolic murmurs (White, 1927; Fahr, 1930; Bass et al., 1933; Shapiro, 1939; White et al., 1942; Baker et al., 1943; Levy et al., 1943; Sodeman, 1944; and Master, 1948). It has been found that they are common in patients without evidence of cardiac disease, and the importance of considering factors other than organic ...
متن کاملEvaluation of aortic stenosis by spectral analysis of the murmur.
A relation between the peak transaortic pressure gradient and the frequency content of the murmur (r = 0.79) was demonstrated in a prospective "test" set of 50 patients with the clinical diagnosis of aortic stenosis. After heart sounds were recorded and digitized, three segments of the systolic murmur were isolated and analyzed by fast Fourier transform technique. An average frequency spectrum ...
متن کاملA study of Duroziez's murmur of aortic insufficiency in man utilizing an electromagnetic flowmeter.
a large amount of retrograde flow in the femoral artery. Those subjects without significant aortic insufficiency and no Duroziez's murmur had little or no backflow. When only a moderate amount of aortic insufficiency was present, the correlation was less satisfactory. In some subjects who had femoral backflow, a second recording was made from the femoral artery after the aortic valve had been r...
متن کاملDetection of Cardiac Murmur
The project is focused around designing a system that detects the cardiac murmur. So much work has already done in this field and all are efficient but when it comes to cost all of them seems to be costly for a normal people. Thus a system is to be designed that detects the cardiac murmur easily and that is simple to construct and operate. The whole concentration is on accuracy satisfaction and...
