The orthogonal electrocardiogram in left ventricular hypertrophy.

Electrocardiographic left ventricular hypertrophy is not associated with increased in-hospital adverse events in patients experiencing first non-ST segment elevation myocardial infarction: A single center study

Background: There is conflicting data about prognostic implication of electrocardiographic (ECG) left ventricular hypertrophy (LVH) in patients with first non- ST-segment elevation myocardial infarction (NSTEMI). We aimed to examine the association of left ventricular hypertrophy (LVH) on admission electrocardiogram with adverse outcomes in patients with NSTEMI. Methods: In the present study, ...

Comparison of a good orthogonal lead system and one additional chest lead with the conventional 12-lead electrocardiogram.

In a study of the McFee-Parungao system of orthogonal lead electrocardiography 452 electrocardiograms were recorded on 111 normal subjects and 201 patients with cardiovascular disease and abnormalities in the conventional 12-lead electrocardiogram. Comparison of the two lead systems and evaluation of criteria for the electrocardiographic diagnosis of normal, right ventricular hypertrophy, left ...

The missing waveform information in the orthogonal electrocardiogram (Frank leads). II. Diagnosis of left ventricular hypertrophy and myocardial infarction from "total" surface waveform information.

How reliable is the electrocardiogram in detecting left ventricular hypertrophy in hypertension?

This paper assesses the sensitivity and specificity of the electrocardiogram in detecting left ventricular hypertrophy in 75 hypertensive patients. Each patient underwent a 12 lead electrocardiogram and echocardiogram. Left ventricular mass index, using echocardiogram, was calculated according to the Penn convention and left ventricular hypertrophy was assessed by standard electrocardiographic ...

Effect of Carvacrol on Catalase Activity and mRNA Expression Following Left Ventricular Hypertrophy in Rats

Background and Aims: Cardiac hypertrophy is a compensatory augmentation response of the heart due to pressure overload that can lead to heart failure. Carvacrol is considered as the major compound of many plants, that possesses strong antioxidant properties. The present study aimed to evaluate effect of carvacrol on catalase activity and mRNA expression following left ventricular hypertrop...

Computer interpretation of pediatric orthogonal electrocardiograms: statistical and deterministic classification methods.

Statistical multivariate and conventional deterministic methods of computerized interpretation of the electrocardiogram (ECG) were compared in the analysis of 1711 pediatric orthogonal ECGs validated by nonelectrocardiographic criteria on the basis of clinical and anatomic diagnoses. Among 642 children catheterized for the evaluation of congenital heart disease, there were 140 patients with lef...
