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...

We attempted to evaluate whether subjects who exhibit prolonged corrected QT (QTc) interval (≥440 ms in men and ≥460 ms in women) on ECG, with and without ECG-diagnosed left ventricular hypertrophy (ECG-LVH; Cornell product, ≥244 mV×ms), are at increased risk of stroke. Among the 10 643 subjects, there were a total of 375 stroke events during the follow-up period (128.7±28.1 months; 114 142 per...

BACKGROUND High-risk individuals for CHD could be diagnosed by some non-invasive and low-priced techniques such as Minnesota ECG coding and rose angina questionnaire (RQ). OBJECTIVES The present study aimed at determining the risk of incident CHD according to ECG and RQ besides diabetes and other metabolic risk factors in our population. METHODS Participants comprised of 5431 individuals ag...

Wearable ECG devices are used in combination with smartphones to capture, analyze and transmit ECG data to far away hospitals where doctors analyze, diagnose and provide necessary patient feedback. ECG electrode cable misplacement is a significant challenge when untrained patients use them, especially among rural population. Lead misplacement algorithms exists for standard ECG electrode positio...

SCP-ECG (Standard Communications Protocol for Computer-Assisted Electrocardiography) is a signalspecific format drawn by the European Committee for Standardization with the goal to be widely used in the ECG field. According to it, a software prototype has been developed and tested in a complex clinical setting. The program extracts information related to the patient, the global measurements, th...

ECG contains very important clinical information about the cardiac activities of heart. The features of small variations in ECG signal with time-varying morphological characteristics needs to be extracted by signal processing method because there are not visible of graphical ECG signal. Small variations of simulated normal and noise corrupted ECG signal have been extracted using FFT and wavelet...
