ST-Elevation Myocardial Infarction simulations

The authors present the methods of ECG signal simulation especially ST-Elevation Myocardial Infarction known as STEMI. It occurs in the case of blood flow around and towards heart problem. It is strongly associated with a heart attack due to low level of oxygen transported to the heart muscle. The most common symptoms of this disease are chest pain, breath shortness or sweating. There are many symptoms of STEMI but the most characteristic feature is a line change between the QRS complex and T wave which are considered by the authors. The obtained results are compared with actual signals from three leads of ECG Holter, or scanned signals digitalized to formatted files. All simulations, results and analyses are made used of in the applications created by the authors. 1 ECG signal simulation Good understanding of wave features allows to create a method for ECG signal simulation. Based on the normal heart conditions examination performed by the basic ECG register, the authors decided to develop a model which contains three different cycles with a possibility of their expansion into long signals. The extended length is needed for a time frequency analysis, but in this model it only multiplies the features of three basic cycles. The simulator changes a signal using mathematical algorithms, generating curves almost in unrestricted amount of ∗[email protected] Pobrane z czasopisma Annales AIInformatica http://ai.annales.umcs.pl Data: 06/04/2018 04:56:18
