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 ...
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...
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...
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...
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...
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...
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 ...
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...
