    • 摘要: Cardiovascular manifestations and electrocardiographic abnormalities have been reported among some prevalent infections in tropical regions,which lead to a great amount of morbidity and mortality.The major infectious diseases include chikungunya,dengue fever,H1N1 influenza,and coronavirus disease-19(COVID-19)in the viral category,leptospirosis,salmonellosis,scrub typhus and tuberculosis in the bacterial category,and malaria in the protozoan parasite category.All these infirmities constitute a foremost infection burden worldwide and have been linked to the various cardiac rhythm aberrancies.So we aimed to identify and compile different studies on these infections and associated acute electrocardiographic(ECG)changes.The search was made in online international libraries like PubMed,Google Scholar,and EMBASE,and 38 most relevant articles,including original research,systematic reviews,and unique case reports were selected.All of them were evaluated thoroughly and information regarding ECG was collected.Myocarditis is the predominant underlying pathology for rhythm disturbance and can be affected either due to the direct pathogenic effect or the abnormal immune system activation.ECG variabilities in some infections like chikungunya,scrub typhus,and leptospirosis are associated with longer hospital stay and poor outcome.Tropical infective diseases are associated with prominent acute cardiac rhythm abnormalities due to myocarditis,which can be identified preliminarily by ECG changes.

    • 摘要: Automatic biomedical signal recognition is an important processfor several disease diagnoses. Particularly, Electrocardiogram (ECG) is commonly used to identify cardiovascular diseases. The professionals can determine the existence of cardiovascular diseases using the morphological patternsof the ECG signals. In order to raise the diagnostic accuracy and reduce thediagnostic time, automated computer aided diagnosis model is necessary. Withthe advancements of artificial intelligence (AI) techniques, large quantity ofbiomedical datasets can be easily examined for decision making. In this aspect,this paper presents an intelligent biomedical ECG signal processing (IBECGSP) technique for CVD diagnosis. The proposed IBECG-SP technique examines the ECG signals for decision making. In addition, gated recurrent unit(GRU) model is used for the feature extraction of the ECG signals. Moreover,earthworm optimization (EWO) algorithm is utilized to optimally tune thehyperparameters of the GRU model. Lastly, softmax classifier is employedto allot appropriate class labels to the applied ECG signals. For examiningthe enhanced outcomes of the proposed IBECG-SP technique, an extensivesimulation analysis take place on the PTB-XL database. The experimentalresults portrayed the supremacy of the IBECG-SP technique over the recentstate of art techniques.

    • 摘要: 目的:提出一种基于经验小波变换(empirical wavelet transform,EWT)的预处理方法,以实现心电(electrocardiogram,ECG)信号中基线漂移噪声的去除。方法:首先通过傅里叶变换将时域ECG信号转换为频域信号,然后选择none(不处理)或使用Gaussian(高斯滤波器)、average(平均过滤器)、closure(形态闭合算子计算上包络)等正则化方法进行信号预处理。其次通过locmaxmin(局部极小极大值)法得到2个频谱分割边界,再通过EWT分解获得噪声主导分量和ECG主导分量。最后对噪声主导分量进行处理,实现ECG信号基线漂移噪声的去除。以相关系数(R)、信噪改善比(SNRimp)、百分比均方根差(PRD)和均方误差(MSE)作为性能指标进行定量分析,筛选出最优正则化方法,然后再对最优方法进行定性分析。结果:实验结果表明,使用average正则化方法预处理的EWT(average-EWT)方法作为ECG信号基线漂移噪声去除预处理方法,具有最优的定量分析结果,并且能够实现波形形态差异较大的ECG信号基线漂移噪声的去除。结论:基于average正则化方法预处理的EWT(average-EWT)方法能够将噪声主导信号分量有效分解,在去除基线漂移噪声、有效还原ECG信号中具有可行性。

    • 摘要: Clinical Study and automatic diagnosis of electrocardiogram(ECG)data always remain a challenge in diagnosing cardiovascular activities.The analysis of ECG data relies on various factors like morphological features,classification techniques,methods or models used to diagnose and its performance improvement.Another crucial factor in themethodology is howto train the model for each patient.Existing approaches use standard training model which faces challenges when training data has variation due to individual patient characteristics resulting in a lower detection accuracy.This paper proposes an adaptive approach to identify performance improvement in building a training model that analyze global trainingmethodology against an individual training methodology and identifying a gap between them.We provide our investigation and comparative study on these methods and model with standard classification techniques with basic morphological features and Heart RateVariability(HRV)thatmay aid real time application.This approach helps in analyzing and evaluating the performance of different techniques and can suggests adoption of a best model identification with efficient technique and efficient attribute set for real-time systems.

    • 摘要: In this era of electronic health,healthcare data is very important because it contains information about human survival.In addition,the Internet of Things(IoT)revolution has redefined modern healthcare systems and management by providing continuous monitoring.In this case,the data related to the heart is more important and requires proper analysis.For the analysis of heart data,Electrocardiogram(ECG)is used.In this work,machine learning techniques,such as adaptive boosting(AdaBoost)is used for detecting normal sinus rhythm,atrial fibrillation(AF),and noise in ECG signals to improve the classification accuracy.The proposed model uses ECG signals as input and provides results in the form of the presence or absence of disease AF,and classifies other signals as normal,other,or noise.This article derives different features from the signal using Maximal Information Coefficient(MIC)and minimum Redundancy Maximum Relevance(mRMR)technique,and then classifies them based on their attributes.Since the ECG contains some kind of noise and irregular data streams so the purpose of this study is to remove artifacts from the ECG signal by deploying the method of Second-Order-Section(SOS)(filter)and correctly classify them.Several features were extracted to improve the detection of ECG data.Compared with existing methods,this work gives promising results and can help improve the classification accuracy of the ECG signals.

    • 摘要: ST-segment elevation myocardial infarction (STEMI) is an important, life-threatening diagnosis that requires quick diagnosis and treatment, characteristic ECG of which shows ST-segment elevation. Unfortunately, ST-segment elevation is nonspecific, which can be misleading if not careful to be interpreted, as in this case of hypercalcemia seen by us. A 48-year-old male was admitted to our emergency department with recurrent chest pain, nausea and vomiting. Medical history includes hypertension and diabetes. ST-segment elevation in V1 - V4 mimicking STEMI was present on admission. However, immediate coronary angiography revealed nearly normal coronary arteries, his troponin was negative in 6 hours and calcium was 2.95 mmol/L. It was thought that the ECG changes were not indicative of cardiac ischemia but hypercalcemia. He was managed with calcium reduction treatment such as intravenous normal saline and furosemide, with subsequent resolution of ST-segment changes.
