In this paper, an automatic classifier has been developed using Feed Forward Neural Network (FFNN) to classify the ECG signals between different heartbeats. Here, the classifier is trained independently bymorphological, heartbeat interval features and temporal features using Particle Swarm Optimization (PSO) and Gravitational Search Algorithm (GSA). The trained classifier then classifies the be...

Atrial fibrillation (AF) affects subjects with Chagas' disease and is an indicator of poor prognosis. We investigated clinical, echocardiographic and electrocardiographic variables of Chagas' disease in a long-term longitudinal study as predictors of a new-onset AF episode lasting >24 h, nonfatal embolic stroke and cardiac death. Fifty adult outpatients (34 to 74 years old, 62% females) staged ...

The aim of this study is to address a new feature extraction method in the area of the heart arrhythmia classification based on a metric with simple mathematical calculation called Curve-Length Method (CLM). In the presented method, curve length of the under study excerpted segment of signal is considered as an informative feature in which the effect of important geometric parameters of the ori...

In this paper, we analyse features from R waveform of electrocardiogram (ECG) and arterial blood pressure (ABP) signals for classifying premature heart beats. Detection of these beats is important as they could be a pre-cursor for serious arrhythmias. The fusion of ECG and ABP signals to detect premature heart beats are relatively new as most methods use only ECG signals. Two new features, mobi...

Placement of an implantable cardioverter-defibrillator (ICD) is the only powerful treatment modality for Brugada syndrome in patients presenting with ventricular fibrillation (VF). For those whose first presentation is an electrical storm, pharmacologic therapy is typically used to control VF followed by ICD implantation. We report an alternative approach whereby, before ICD implantation, emerg...

Premature ventricular complex (PVC) frequency and duration have important clinical implications. PVC induced cardiomyopathy is a potentially reversible condition in which cardiac function impaired by the occurrence of frequent PVCs. In addition, PVCs may result from acquired cardio toxicity and/or predictive for life-threatening arrhythmias. detection using computationally simple techniques has...
