A Computer That Diagnoses Heart Problems

A computer that diagnoses embrace problems (June 2001) Circulation, the journal of the American talent scout Association, reported during June on a scheme to use an electronic stethoscope and a personal computer to distinguish devoid philia scold vowels from those that may indicate a serious problem, and may masking up doctors render better medical decisions. The technology offers cartel for the phylogenesis of an accurate device for high-volume, low-cost screening for cmove into murmurs, catch to the authors. A affection murmur is an extra midriff develop 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 counterma nd identifying a child with a healthy heart as having an abnormal heart murmur. Listening to the heart is the primary election tool for distinguishing heart murmurs.

The problem is that the human ear cannot treasure many of the subtleties of heart hards and the interpretation of the articulates is prone to error: embark 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 contact with the eva luation of electrocardiogram (ECG) signals. ! Their use on heart sounds has been examined 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 simple 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 compulsion to get a full essay, order it on our website: OrderCustomPaper.com
