An algorithm to determine quality of ECGs can enable inexperienced nurses and paramedics to record ECGs of sufficient diagnostic quality. We propose an algorithm that can assess the quality of an ECG designed for an Android-based platform. The algorithm is based on previously established ECG quality metrics for quantifying ECG quality but designed in a way to make it efficient ...

The article emphasizes clinical and prognostic significance of non-linear measures of the heart rate variability (HRV). It was applied on the group of patients with stable coronary heart disease (CHD) and arterial hypertension (AH) before and after 6 months treatment by amlodipine besylate (5 mg daily). Two different methods were applied: Hurst exponent (H) and detrended fluctuation analysis (DFA). Hurst ...

An algorithm to determine quality of ECGs can enable inexperienced nurses and paramedics to record ECGs of sufficient diagnostic quality. We propose an algorithm that can assess the quality of an ECG designed for an Android-based platform. The algorithm is based on previously established ECG quality metrics for quantifying ECG quality but designed in a way to make it efficient to run on a mobile platform. Using the training data set the proposed algorithm obtained a sensitivity of 91% and a specificity of 85%. Testing against the test data sets, resulted in a score of 0.88 (events 1 and 2) and 0.79 (events 3). The proposed algorithm discriminates between ECGs of good and bad quality, which could help diagnose patients earlier and reduce associated treatment costs.
The high prevalence of obstructive sleep apnoea (OSA) requires a simplified, unattended screening device that would be useful for diagnosis at the early stage. This study presents a method for screening individual OSA event based on sleep ECG signal. The overnight ECG recordings were divided into 5-second epochs containing normal (N) breathing and onset (O), maximum (M) & termination (T) of OSA events. Power spectral analysis of ECG epochs was employed to extract features. The area under receiver operating characteristics curve was estimated to determine the discrimination capability of each feature (or power in each frequency bin). The maximum ROC areas for N/O, N/M and N/T were found to be 0.78, 0.81,0.71 in the ranges of powers of 57-65 Hz, 52-72 Hz, 52-66 Hz bands respectively. An heuristic rule was applied to recognize the individual OSA events from spectral features of N,O,M,T epochs. Results show good agreement with the original annotations in an overnight sleep study. These results, therefore, could have considerable potential in ECG based screening and can aid sleep specialist in the assessment of patients with suspected sleep apnoea syndrome.
The applcation of the fast Fourier transform in the digital analysis of various biological signals in the frequency domain is well-known. In this paper a method is described for spectrum analysis of respiratory sound using the technique of fast Fourier transform. Results of the application of the method to respiratory sounds of six normal subjects and six tuberculosis patients are presented. Such studies may well prove to be a promising noninvasive diagnostic tool for lung diseases and increase the clinical importance of lung auscultation.
The article emphasizes clinical and prognostic significance of non-linear measures of the heart rate variability (HRV). It was applied on the group of patients with stable coronary heart disease (CHD) and arterial hypertension (AH) before and after 6 months treatment by amlodipine besylate (5 mg daily). Two different methods were applied: Hurst exponent (H) and detrended fluctuation analysis (DFA). Hurst exponent of the R-R series was determined by the range rescaled analysis technique. DFA was used to quantify fractal long- range-correlation properties of heart rate variability. It was found that the short-term fractal scaling exponent (/spl alpha//sub 1/) is significantly lower in patients with CHD, as well as Hurst exponent. But, after 6 months treatment with calcium channel blocker amlodipine besylate the results of HRV are normalize.
The Chagas¿ disease is endemic in all Latin America, affecting millions of people in the continent. In order to diagnose and treat the Chagas¿ disease, it is important to detect and measure the coronary damage of the patient. In this paper, we analyze and categorize patients into different groups based on the coronary damage produced by the disease. Based on the features of the heart cycle extracted using high resolution ECG, a multi-class scheme of error-correcting output codes (ECOC) is formulated and successfully applied. The results show that the proposed scheme obtains significant performance improvements compared to previous works and state-of-the-art ECOC designs.
Analysis of heart rate variation (HRV) has become a popular noninvasive tool for assessing the activities of the autonomic nervous system (ANS). HRV analysis is based on the concept that fast fluctuations may specifically reflect changes of sympathetic and vagal activity. It shows that the structure generating the signal is not simply linear, but also involves nonlinear contributions. These signals are essentially non-stationary; may contain indicators of current disease, or even warnings about impending diseases. The indicators may be present at all times or may occur at random in the time scale. However, to study and pinpoint abnormalities in voluminous data collected over several hours is strenuous and time consuming. This paper presents the continuous time wavelet analysis of heart rate variability signal for disease identification. Phase space plots of heart rate signal for a chosen embedding dimension are compared with the wavelet analysis patterns
Presents some results of the experience of using computerised rhythmocardiography (RCG) apparatus and heart rate variability analysis. This method and its equipment is used in 28 hospitals of the Ural region. The RCG data is comprised of more than 15 thousand RCGs from patients with different forms of cardiovascular disease. The results of this study show that RCG with heart rhythm wave structure analysis using the presented computerised apparatus may be used in practical medicine for nonspecific diagnostics of cardiovascular pathology. This method can decrease nondiagnostic cases of cardiovascular diseases and their complications.
In the past few years a number of algorithms for cardiovascular risk stratification have been proposed to the medical community but a big question has been remained unsolved: From among alternative sets of cardiac risk factors which ones are more significant in cardiac risk stratification? In this paper a hybrid neuro-fuzzy classifier, IRIDIA Method for Neuro-fuzzy Identification and Data Analysis, was applied to determine the cardiac risk stratification. Using the obtained neuro-fuzzy model, sensitivity analysis of cardiac risk factors was derived to sort out cardiac risk factors according their significance - which factor has great effect on cardiac risk.
Right ventricular hypertrophy (RVH) and RV dysfunction are difficult to evaluate due to the complex shape of the RV and prognostic limitations of conventional global function parameters. We used MRI with magnetization tagging to measure 2-D systolic motion and deformation of the right ventricular free wall (RVFW) and septum (SEPT) in 5 patients with RVH secondary to pulmonary hypertension, and 12 normal volunteers (NL). Regional displacement (D) and 2-D principal strains in the short-axis plane were averaged at basal, midventricular and apical levels. SEPT D was severely decreased at all levels in RVH vs. NL (P<0.005). In RVH, RVFW D was higher than SEPT D (P<0.02). The 2-D strains were reduced in SEPT at all levels in RVH vs. NL (P<0.05). This technique may permit the study of progression and regression of RVH in various disease states.
