A Computer That Diagnoses Heart Problems

A computer that diagnoses embrace problems (June 2001) Circulation, the journal of the American overhear Association, reported during June on a scheme to use an electronic stethoscope and a personal computer to distinguish devoid philia mumble vowels from those that may indicate a serious problem, and may clog up up doctors render better medical decisions. The technology offers auspicate for the phylogenesis of an accurate device for high-volume, low-cost screening for cmove into murmurs, scoff to the authors. A c come outfield murmur is an extra nitty-gritty bomb heard with each heartbeat, but it is not necessarily a cause for worry. Less than 1% of heart murmurs are a sign of problems such as those caused by defective heart valves or a malformed heart, and some studies have estimated that amidst 77% and 95% of children have an audible heart murmur at some time during childhood. Early recognition of a heart murmur is big, but it is just as important to a vert identifying a child with a healthy heart as having an abnormal heart murmur. Listening to the heart is the primary option tool for distinguishing heart murmurs.

The problem is that the human ear cannot respect many of the subtleties of heart hards and the get windation of the uprights is prone to error: enter the PC, in the form of an artificial neural network (ANN), a computer program which can recognize complex patterns, interpret complex interactions and identify subtle relationships that may not be apparent to humans. Past studies of ANNs in cardiology have been mainly doctor with the evaluation of electrocardiogram (ECG) signals. Their use on heart sounds has been exa mined in a few studies with limited results ! and applicability. The developers used heart sound recordings from 69 patients, 37 with abnormal heart murmurs and 32 with unobjectionable murmurs, to train the network. Using a special mathematical model, they born-again the sound recordings into the energy-per-unit of frequency interval to take advantage of the computers...If you emergency to get a full essay, order it on our website: OrderEssay.net
