Detection of Cardiac Murmurs
The project describes a system for detecting cardiac murmurs so people are aware about their heart condition. The murmurs are the pathologic heart sounds that are produced because of turbulent blood flow that is enough to cause audible noise. Murmurs can be detected by a stethoscope but the accuracy level is not satisfactory. Different methods have been developed for detection and all are effic...
متن کاملApproach to Cardiac Murmurs
A murmur is a sound generated when blood travels through vessels or valves in a turbulent or energy-dissipating manner. It can be an important clue to a structural abnormality of the cardiovascular system. However, over 50% of people have murmurs during childhood, but less than one percent are associated with congenital heart disease. Thus, the vast majority of murmurs are benign or innocent ra...
متن کاملCardiac Murmurs in the Newborn
rHAT cardiac murmurs are of frequent occurrence during childhood is evident from the statement of Holt and McIntosh (1940) that 50 per cent. of all children have a functional murmur at some time. Several workers have investigated the incidence of cardiac murmurs in the neonatal period. Their results have varied considerably. Seham (1924) found 34 per cent. of newborn infants to have murmurs. Si...
متن کاملDoppler echocardiography. The localization of cardiac murmurs.
SUMMARY A range-gated pulsed Doppler flowmeter has recently been developed that measures the average velocity of blood flow within a small tear-drop shaped (4 mm by 2 mm) sample volume. Unlike the continuous wave Doppler, the distance from the transducer face to the sampling site can be continuously varied by a range adjustment knob. Twenty patients with cardiac murmurs were evaluated in a noni...
متن کاملMastering cardiac murmurs: the power of repetition.
BACKGROUND The ability of medical students to recognize heart murmurs is poor (20%), and does not improve with subsequent years of training. A teaching method to improve this skill would be useful. STUDY OBJECTIVES To determine whether intensive repetition of four basic cardiac murmurs improves auscultatory proficiency in medical students. DESIGN Controlled intervention study. SUBJECTS Fi...
