Comparison of Electrocardiographic Criteria for Identifying Left Ventricular Hypertrophy in Athletes from Different Sports Modalities

Clinics; 72 (6), 2017
OBJECTIVES: In athletes, isolated electrocardiogram high voltage criteria are widely used to evaluate left ventricular hypertrophy, but positive findings are thought to represent normal electrocardiogram alterations. However, which electrocardiogram criterion can best detect left ventricular hypertrophy ...

Onda de Osborn asociada a hipotermia sin bradicardia presente. A propósito de un caso
Osborn´s wave associated to hypothermia without the presence of bradycardia. A propos of a case

Rev. medica electron; 39 (3), 2017
La onda J de Osborn es una deflexión que se inscribe en el electrocardiograma (ECG) entre el complejo QRS y el inicio del segmento ST. La onda J tiene una alta sensibilidad y especificidad en la hipotermia, aunque no es patognomónica. Se han descrito casos en la hemorragia subaracnoidea, la hipercalcem...

Cardiomiopatia de Takotsubo com Requisição de Oxigenação Extracorpórea por Membrana (ECMO) Após Cirurgia de Mixoma Atrial

Aplicabilidade da Cintilografia Miocárdica de Perfusão na Avaliação do Sincronismo Cardíaco

ABC., imagem cardiovasc; 30 (2), 2017
Com o objetivo de avaliar de modo sistemático a literatura sobre a aplicabilidade da cintilografia de perfusão do miocárdio com análise de fase na investigação do dissincronismo cardíaco e na seleção de pacientes para terapia de ressincronização cardíaca (TRC), foi realizada uma revisão de a...

Physical and electrocardiographic evaluation of horses used for wagon traction

The objective of this research was to evaluate the electrocardiogram (ECG) of horses used for wagon traction and to compare the results with the parameters obtained from inactive horses or horses submitted to a training routine. Fifty-six 3-15-year-old healthy horses (22 females and 34 males) were divide...

A Multivariate Model for Prediction of Obstructive Coronary Disease in Patients with Acute Chest Pain: Development and Validation

Arq. bras. cardiol; 108 (4), 2017
Abstract Background: Currently, there is no validated multivariate model to predict probability of obstructive coronary disease in patients with acute chest pain. Objective: To develop and validate a multivariate model to predict coronary artery disease (CAD) based on variables assessed at admission to...

Evaluation of electrocardiographic parameters in patients with hearing loss genotyped for the connexin 26 gene (GJB2) mutations

Abstract Introduction: Several studies have associated congenital sensorineural hearing loss in children with prolongation of the cardiac parameter QTc. The cause of this association is unknown. At the same time, mutations in GJB2, which encodes connexin 26, are the most common cause of congenital heari...

Síndrome de Kounis, ¿el tipo de infarto olvidado?

Rev. colomb. cardiol; 24 (2), 2017
Sr. Editor: El síndrome de Kounis es una entidad infrecuente y potencialmente infradiagnosticada en la práctica clínica. Se considera relevante el conocimiento de esta patología debido a la necesidad de pensar en ella ante pacientes que desarrollan un síndrome coronario agudo en el contexto de una ...

Distorsión morfológica isquémica de la onda T en la centellografía de perfusión miocárdica con estrés vasodilatador
Ischemic T wave distortion associated with vasodilator-stress myocardial perfusion imaging

Medicina (B.Aires); 77 (2), 2017
Los protocolos que utilizan vasodilatadores para inducir isquemia en la centellografía de perfusión miocárdica han demostrado una exactitud diagnóstica elevada e incidencia muy baja de complicaciones graves. Sin embargo, el significado fisiológico y valor diagnóstico de diversas alteraciones electr...
