THE DURATION OF NORMAL HEART SOUNDS

assessing methods of normal heart sounds

listen to the heart sounds gives us valuable information about existence of disorder in heart rate and rhythm, ventricular fibrillation and movement of blood through valves. this required a lot of skills. so it is necessary to understand and apply these skills for nurses in cardiac and intensive care. abnormal sounds can be recognized by them. for facilitation this work, nurses should be have i...

The Heart Sounds in Normal and Pathological Conditions

A Hybrid Model of Heart Anomalies Detection by Processing Heart Sounds

​Introduction: Different factors are effective in detecting heart abnormalities. The greater the number of these factors, the greater the uncertainty in the detection of heart abnormalities. In the uncertainty condition in response of prediction model, the fuzzy systems are one of the most effective methods for generating an acceptable response. Method: In this applied study, 3240 records rela...

Determining the effective features in classification of heart sounds using trained intelligent network and genetic algorithm

Heart diseases are among the most important causes of mortality in the world, especially in industrial countries. Using heart sounds and the features extracted from them are among the non-aggressive diagnosis and prognosis methods for heart diseases. In this study, the time-scale, Cepstral, frequency, temporal and turbulence features are saved and extracted from the heart sounds, and then they ...
