1. Non-invasive ECG recording and QT interval correction assessment in anesthetized rats and mice
RESUMO: Ratos e camundongos são as espécies mais comumente utilizadas em estudos experimentais de eletrofisiologia cardíaca. O registro do eletrocardiograma (ECG) é de suma importância para o monitoramento de arritmias e função cardíaca em vários modelos de patologias. No entanto, a falta de valores de referência padronizados e a fórmula de corre�

2. Morbidity of Chagas heart disease in the microregion of Rio Negro, Amazonian Brazil: a case-control study
A case-control study on the morbidity of Chagas heart disease was carried out in the municipality of Barcelos in the microregion of the Rio Negro, state of Amazonas. One hundred and six individuals, who were serologically positive for Trypanosoma cruzi infection, as confirmed by at least two techniques with different principles, were matched according to age

3. Desenvolvimento, caracterizacao e aplicacao da matriz FTO/POLI(3-aminofenol) na deteccao de marcador de lesao cardiaca por fotoluminescencia de quantum dots
The heart is a vital organ propelling blood, that carries oxygen and nutrients throughout the body, but whenever these components do not reach it due to arterial obstruction, there is an electrical instability in the process of contraction of the muscle, causing arrhythmias that often, in less than an hour, causes acute myocardial infarction. The problem and

4. Deep breathing heart rate variability is associated with respiratory muscle weakness in patients with chronic obstructive pulmonary disease
BACKGROUND: A synchronism exists between the respiratory and cardiac cycles. However, the influence of the inspiratory muscle weakness in chronic obstructive pulmonary disease (COPD) on cardiac autonomic control is unknown. The purpose of the present investigation was to evaluate the influence of respiratory muscle strength on autonomic control in these pati

5. SYSTEM FOR CONFORMITY ASSESSMENT OF ELECTROCARDIOGRAPHS / SISTEMA PARA AVALIAÇÃO DA CONFORMIDADE DE ELETROCARDIÓGRAFOS
Com a motivação de contribuir para a garantia da confiabilidade metrológica de eletrocardiógrafos, o presente trabalho tem por objetivo desenvolver um sistema para avaliação da conformidade de ECGs com base na norma IEC 60601-2-51 e na Recomendação R90 (1990) da OIML. Desde 1995, as normas da série IEC 60601 vêm sendo utilizadas como base para regu

6. ClassificaÃÃo automÃtica de cardiopatias baseada em eletrocardiograma
This work is dedicated to study of the recognition and classification of cardiac disease, diagnosised through the electrocardiogram â ECG. This examination is normally used in heart medical center, emergency, intensive therapy, and with complement diagnosis in heart disease as: acute myocardium infarction, bundle block branches, hypertrophy and others. The

7. An analysis of the electrocardiogram QT interval
No reports testing the efficacy of the use of the QT/RR ratio <1/2 for detecting a normal QTc interval were found in the literature. The objective of the present study was to determine if a QT/RR ratio <=1/2 can be considered to be equal to the normal QTc and to compare the QT and QTc measured and calculated clinically and by a computerized electrocardiograp

11. Prolonged P-R interval in a male with 47,XYY karyotype.
A 47,XYY male with an extremely prolonged P-R interval (0.42 sec) on the electrocardiograph is described. There was also a secondary R wave in lead V1. He had no past history of heart disease and no cardiac abnormality on physical examination.

12. A syndrome of hypogonadism, alopecia, diabetes mellitus, mental retardation, deafness, and ECG abnormalities.
A distinct and previously undescribed syndrome has been observed in six Saudi Arabian patients from two highly inbred families. The parents were normal, indicating an autosomal recessive pattern of inheritance. All the patients have a distinctive facial appearance, hypogonadism, sparse or absent hair, diabetes mellitus, mental retardation, mild deafness, and
