Estimación de la edad cardiovascular a partir de tacogramas de 2 minutos de duración mediante Análisis de Cuantificación de Recurrencias
Estimation of cardiovascular age from 2 minute tachograms via Recurrence Quantification Analysis

Se han reportado diferentes intentos de estimar la edad cardiovascular a partir de señales electrofisiológicas. Las propuestas publicadas presentan inconvenientes para su aplicación en la práctica clínica. Nos hemos propuesto estimar la edad cardiovascular a partir de tacogramas de 2 minutos de dura...

Semiologia Cardiovascular: As Personalidades por Detrás dos Epônimos

Desde seus primórdios, a medicina sempre se baseou na observação de sinais e achados específicos de pacientes doentes. A semiologia é, portanto, um estudo milenar. A semiologia cardíaca, apesar de mais recente, é mais complexa no seu aprendizado devido à dificuldade na interpretação dos achados...

Is the algorithm used to process heart rate variability data clinically relevant? Analysis in male adolescents

Einstein (Säo Paulo); 14 (2), 2016
ABSTRACT Objective To analyze whether the algorithm used for the heart rate variability assessment (fast Fourier transform versus autoregressive methods) influenced its association with cardiovascular risk factors in male adolescents. Methods This cross-sectional study included 1,152 male adolescents...

Electrocardiographic parameters of the American Miniature Horse: influence of age and sex

Pesqui. vet. bras; 36 (6), 2016
The veterinary cardiology has growing importance in equine medicine. There are studies of standardization of electrocardiographic parameters of many races, according to their stature and ability. However, no studies are in the literature with the American Miniature Horse. To evaluate the electrocardiogra...

Redes neuronales: aplicación de una herramienta computacional en Cardiología clínica

Rev. colomb. cardiol; 21 (4), 2014
Si inicialmente las ciencias computacionales y los programas informáticos se introdujeron en la práctica médica solo en procedimientos básicos que incluían recolección de datos y abordajes estadísticos, de donde de la disciplina computacional solo se especulaban nuevos roles de interacción entre ...

Applying the 3-element windkessel model to photoplethysmographic signals. Gender differences and age correlation

Automatically averaged photoplethysmographic (PPG) signals were fit to a 3-element windkessel model using a Gauss-Newton optimization algorithm. Data corresponded to 78 healthy subjects (ages from 8 to 87 years). Unlike other reports, two phase velocities are also estimated from the model. Gender differe...
