Definición de Ortostatismo

Respuesta vasovagal cardioinhibitoria durante la prueba de mesa basculante. En total se incluyeron 57 pacientes en el grupo marcapasos y 54 pacientes en el grupo control. Maniobra de Valsalva La maniobra de Valsalva se utiliza para evaluar la integridad de los arcos reflejos arteriales y cardiopulmonares.

La prueba se considera positiva si se produce un incremento mayor de 20 latidos por minuto en ritmo sinusal con una dosis menor de 0,5 mg. La prueba se considera positiva cuando la fase tres es mayor a 10 segundos considerando posibles escapes ventriculares y es negativa cuando no existe fase 3 o la misma es menor a 10 segundos. Sin embargo, existe una constante controversia en cuanto al valor de la adenosina para identificar pacientes candidatos al implante de marcapasos.

A proper identification will allow a precise etiologic approach and the optimization of delivery of health resources.

Once knowing the classification of syncope; it is the clinical interrogatory what enables to discriminate which of these patients present with a neurogenic mediated syncope or a cardiac mediated syncope.

The use of diagnostic methods such as the tilt test, will clarify what type of neurally mediated syncope predominates in the patient. The electrocardiogram is the cornerstone in the identification of those patients who had a true episode of self-limited or aborted sudden death as the first manifestation of their syncope, a fact which provides prognostic and therapeutic information that will impact the morbidity and mortality.
