Electrocardiogram (ECG) is one of the most common biological signals which play a significant role in the diagnosis of heart diseases. One of the most important parts of ECG signal processing is interpretation of QRS complex and obtaining its characteristics. R wave is one of the most important sections of this complex, which has an essential role in(More)
BACKGROUND Ischemic heart disease is one of the common fatal diseases in advanced countries. Because signal perturbation in healthy people is less than signal perturbation in patients, entropy measure can be used as an appropriate feature for ischemia detection. METHODS Four entropy-based methods comprising of using electrocardiogram (ECG) signal(More)
Ischemia means lack of oxygen due to insufficient blood circulation. Cardiac ischemia disease, which is one of the common fatal diseases in advanced countries, is a condition due to imbalance between supply and demand of oxygen. In this study the existence of ischemia is considered using entropy measure. Since signal perturbation in healthy people is less(More)
Electrocardiogram (ECG) signal is one of the most important and most used biologic signals which have a significant role in diagnosis of heart diseases. Extraction of QRS complex and obtaining its characteristics is one of the most important parts in ECG signal processing. R wave is one of the main sections of QRS complex which has the essential role in(More)
Cardiac ischemia is one of the major causes of mortalities in the world. This disease includes a wide range of temporarily disorders such as insufficient blood circulation to myocardium, which leads to myocardial infarction, and consequently, sudden death. Recording electrocardiogram (ECG) signal has an important role in diagnosis of cardiac disease due to(More)
Electrocardiogram (ECG) signal involves significant information about heart state and is one of the common tools for cardiologist in diagnosis of heart failures. Using adaptive filters for filtering this signal, which inherently has nonstationary features, is used as one of the known methods. In this paper, the wavelet transform and also a neural network(More)
