Intervenciones de enfermería en la toma de electrocardiograma, círculo torácico y medrano / Nursing interventions in making electrocardiogram, thoracic circle and Medrano", "_i": "

Aun después del advenimiento de métodos innovadores de mapeo electrocardiográfico tridimensional, el electrocardiograma conserva su significado central en el diagnóstico cardiológico y continúa vigente para orientar el tratamiento de los pacientes cardiópatas. El electrocardiograma ya sea de 12 derivaciones, círculo torácico o Medrano, refleja la actividad eléctrica del corazón y por lo tanto brinda información acerca de la función cardiaca, se imprime sobre un papel cuadriculado de modo que se obtiene un registro continuado de la actividad cardiaca. En la práctica diaria, el profesional de enfermería representa una parte fundamental en la detección oportuna de enfermedades o complicaciones de las mismas, por lo tanto la correcta toma del electrocardiograma es indispensable para obtener un registro de calidad que contribuya con el tratamiento de un paciente y por ende con el mejoramiento de su salud.

Even after the advent of innovative methods for mapping three-dimensional, electrocardiogram its central significance in the cardiological diagnosis and remains in force to guide the treatment of cardiac patients. The electrocardiogram either 12 leads, chest circle or Medrano, reflects the electrical activity of the heart and therefore provides information on cardiac function, is printed on graph paper so that a continuous recording of cardiac activity is obtained. In daily practice, the nurse is a fundamental part in the early detection of diseases or complications thereof therefore correct decision electrocardiogram is essential to obtain a record of quality that contribute to the treatment of a patient and thus to improving your health.

Performance in working memory and attentional control is associated with the rs2180619 SNP in the CNR1 gene.

Individual differences in cognitive performance are partly dependent, on genetic polymporhisms. One of the single-nucleotide polymorphisms (SNP) of the CNR1 gene, which codes for cannabinoid receptor 1 (CB1R), is the rs2180619, located in a regulatory region of this gene (6q14-q15). The alleles of the rs2180619 are A > G; the G allele has been associated with addiction and high levels of anxiety (when the G allele interacts with the SS genotype of the 5-HTTLPR gene). However, GG genotype is observed also in healthy subjects. Considering G allele as risk for 'psychopathological conditions', it is possible that GG healthy subjects do not be addicted or anxious, but would have reduced performance, compared to AA subjects, in attentional control and working memory processing. One hundred and sixty-four healthy young Mexican-Mestizo subjects (100 women and 64, men; mean age: 22.86 years, SD=2.72) participated in this study, solving a task where attentional control and working memory were required. GG subjects, compared to AA subjects showed: (1) a general lower performance in the task (P = 0.02); (2) lower performance only when a high load of information was held in working memory (P = 0.02); and (3) a higher vulnerability to distractors (P = 0.03). Our results suggest that, although the performance of GG subjects was at normal levels, a lower efficiency of the endocannabinoid system, probably due to a lowered expression of CB1R, produced a reduction in the performance of these subjects when attentional control and working memory processing is challenged.
