BACKGROUND Prolonged-QT commonly coexists in the ECG with left ventricular hypertrophy (ECG-LVH). However, it is unclear whether to what extent QT prolongation coexisting with ECG-LVH can explain the prognostic significance of ECG-LVH, and whether prolonged-QT coexisting with ECG-LVH should be considered as an innocent consequence of ECG-LVH. METHODS AND RESULTS The study population consisted...

Electrocardiogram (ECG) signals contain a great deal of essential information which can be utilized by physicians for the diagnosis of heart diseases. Unfortunately, ECG signals are inevitably corrupted by noise which will severely affect the accuracy of cardiovascular disease diagnosis. Existing ECG signal denoising methods based on wavelet shrinkage, empirical mode decomposition and nonlocal ...

We have developed ethylenedicysteine-glucosamine (ECG) as an alternative to (18)F-fluoro-2-deoxy-D-glucose ((18)F-FDG) for cancer imaging. ECG localizes in the nuclear components of cells via the hexosamine biosynthetic pathway. This study was to evaluate the feasibility of imaging mesothelioma with (99m)Tc-ECG and (68)Ga-ECG. ECG was synthesized from thiazolidine-4-carboxylic acid and 1,3,4,6-...

We are Using an individual’s electrocardiogram (ECG) as a means for checking individuals heart functioning and abnormalities (diseases) occurred in it. However, the presence of noise in an ECG trace complicates the analysis of ECG signal for identification of functioning and abnormalities in the heart. The primary noise sources in ECG are power line interference, electromyography (EMG) noise, e...

Adoption of compression technology is often required for wireless cardiovascular monitoring, due to the enormous size of electrocardiogram (ECG) signal and limited bandwidth of Internet. However, compressed ECG must be decompressed before performing human identification using present research on ECG based biometric techniques. This additional step of decompression creates a significant processi...

Electrocardiography (ECG) is an ubiquitous vital sign health monitoring method used in the modern healthcare systems. Different designs of ECG system have been developed as alternatives to the common twelve-lead ECG systems. The recent approaches of the ECG system are focusing on the signal quality, portability and power consumption. In this work, an ECG sensing system is developed with capacit...

The recognition of data from the electrocardiogram (ECG) is the important area of the biomedical signal processing. Identification of ECG signals in real time is closely related to the classification of the patient's diagnosis, inspected for the purpose of diagnosis of the cardiac status. In our paper we analyze the suitable alorithms for the extraction of QRS complex from the raw ECG data. Thi...

Electrocardiogram (ECG) databases play an important role in medical research, pharmaceutical research, medical education and health care. Due to growing demands in research, training, and health care, designing and managing such ECG databases has become a complex problem. This paper reports on the new design approach and the new application model of the Philips ECG Management System (EMS). The ...

Background Accurate ECG R-wave detection is crucial for cardiac gating in MRI. However, in high-field MRI systems, it is hard to detect R-waves in ECG signals accurately, because the amplitude of the ECG signal may be smaller than that of the noise induced by the MRI system. To overcome this issue, existing studies have focused on (a) acquiring additional ECG signals or on (b) improving the R-w...

Conventional ECG still plays an important role in the overall knowledge of Chagas' cardiopathy, because of its importance in longitudinal and epidemiological studies, its diagnostic value, and its utility in prognostic evaluation. The authors discuss these aspects, as well as the use of eCG in the acute phase and the significance of a normal ECG in Chagas' disease. Correlations were made betwee...
