Estimation of heart inclination angle using posteroanterior chest radiograph and comparison with cardiac axis obtained from synthesized vectorcardiogram

IFMBE; 99 (), 2024
ABSTRACT In medical practice, it is common to perform electrocardiography exams and by mathematical transformations to obtain the vectorcardiogram. The vectorcardiogram provides important information for medical diagnosis, such as the angle of inclination of the heart. This article aims to present a meth...

Análise de parâmetros do VCG obtidos a partir de matrizes de transformação do ECG em pacientes com hipertrofia cardíaca
Analysis of VCG parameters obtained from ECG transformation matrices in patients with cardiac hypertrophy

INTRODUÇÃO: O eletrocardiograma (ECG) é uma ferramenta diagnóstica primordial em cardiologia. Através de técnicas de pós-processamento do ECG digital é possível extrair dados do clássico vetorcardiograma (VCG) e ampliar as possibilidades do método. OBJETIVO: Comparar os dados matriciais do ECG...

Inferolateral post-myocardial infarction pseudoaneurysm. A rare case report

ABC., imagem cardiovasc; 33 (1), 2020
ABSTRACT: We report the case of a 76-year-old male patient with a history of ST-segment elevation myocardial infarction (STEMI) for 3 years. He was admitted to the Emergency Room with a new chest pain episode that began 40 days before and was diagnosed with left ventricular (LV) pseudoaneurysm through 3D...

The Association between Reconstructed Phase Space and Artificial Neural Networks for Vectorcardiographic Recognition of Myocardial Infarction

J. eletrocardiol; 51 (3), 2018
Abstract: Myocardial infarction is one of the leading causes of death worldwide. As it is life threatening, it requires an immediate and precise treatment. Due to this, a growing number of research and innovations in the field of biomedical signal processing is in high demand. This paper proposes the ass...
