Sudden cardiac death (SCD) results in millions of deaths annually; as it is a fatal heart abnormality, early prediction SCD could save peoples’ lives to the greatest extent. Symmetry and asymmetry play an important role many fields. Electrocardiograms (ECG) noninvasive process for acquiring electrical activity heart, has both asymmetric non-stationary characteristics; frequently employed diagno...

Analysis of standard clinical electrocardiogram signal is one of the basic routine tests for preliminary screening of cardiac disorders. This work deals with classification of normal and IMI (Inferior Myocardial Infarction) ECGs and presents a method for analysis of Electrocardiogram (ECG) patterns using Cross Correlation. The application of cross correlation to two ECG beats and the cross exam...

Let M be a compact connected special flat affine manifold without boundary equipped with a Gauduchon metric g and a covariant constant volume form. Let G be either a connected reductive complex linear algebraic group or the real locus of a split real form of a complex reductive group. We prove that a flat principal G–bundle EG over M admits a Hermitian–Einstein structure if and only if EG is po...

When rhythmic firing is elicited in cat spinal motoneurons by long-lasting depolarizing currents, the `threshold' voltage from which each spike arises may appear to be quite constant (Fig . IA, arrow) . If one probes for the threshold during the interspike interval (ISI), however, it is seen to fall well below this level, rising towards it later in the ISL Exceptionally large depolarizing after...

The purpose of this study was to investigate the effects of running drills during an interval training program on biomechanical parameters of running. Thirty recreational runners, divided into 2 groups (control group and experimental group [EG]), were submitted to a 15-week interval training, but only EG performed running drills in the training. The test sessions were accomplished before and af...

A wide area of research has been done in the field of noise removal in Electrocardiogram signals.. Electrocardiograms (ECG) play an important role in diagnosis process and providing information regarding heart diseases. In this paper, we propose a new method for removing the baseline wander interferences, based on discrete wavelet transform and Butterworth/Chebyshev filtering. The ECG data is t...

Baseline noise removal from electrocardiogram (ECG) signal is a blind source separation problem. Various noises affect the measured ECG signal. Major ECG noises are baseline noise, electrode contact noise, muscle noise, instrument noise. Baseline noise distorts the low frequency segment of ECG signal. The low frequency segment is s-t segment. This segment is very important and has the informati...

Implantable Devices Bruno Miguel Gil Rosa, Salzitsa Anastasova, and Guang-Zhong Yang demonstrate in article number 2100053 an implantation of a cardiovascular monitoring device inside rodents powered by mobile phone, with physiological signal visualization directly on the app. This is exemplified cover highlight yellow – electrocardiogram red/black signals arterial pulse.

Electrocardiogram (ECG) is an important biomedical signal for analyzing heart activity. Analysis of ECG becomes difficult if noise is augmented with the signal during acquisition. During recent years, several denoising techniques were analyzed within the field of signal processing. In this paper, non local means (NLM) filtering technique is explored for denoising the ECG signal. The noisy ECG s...
