The purpose of this study is to provide a new method for detecting fetal QRS complexes from non-invasive fetal electrocardiogram (fECG) signal. Despite most of the current fECG processing methods which are based on separation of fECG from maternal ECG (mECG), in this study, fetal heart rate (FHR) can be extracted with high accuracy without separation of(More)
The aim of this study is the intelligent recognition of the fetal heart rate and its R-R intervals from noninvasive fetal electrocardiogram signals. The non-value data was first eliminated and the missing data were regenerated based on the statistical distribution of the data. Then, the power line noise and baseline noise are removed. At the next step, a(More)
Introduction: An ECG signal has important information that can help for reflecting cardiac activity of a patient and medical diagnosis. Consistent or periodical heart rhythm disorders can result cardiac arrhythmias so classification algorithm for recognizing arrhythmias with satisfactory accuracy is necessary. Aims: In this study, a robust wavelet based(More)
Introduction: Coronary artery congestion is a heart disease which causes a lack of oxygen and nutrients in the heart, and is felt as chest pain (ischemia disease). Prolonged ischemia can continue until the cells start to dye, which is called myocardial infraction. Aims: We aim to determine the amount of cardiac tissue damage by multi resolution analysis of(More)
In this study, a new method for detection of arterial blood pressure pulses (ABP) is presented. The algorithm employs discrete wavelet transform (DWT) decomposition to extract ABP waveform features. In the proposed method, two strategies are used. In the first strategy, the algorithm uses only the DWT coefficients of ABP. The second strategy which is(More)
