Eletrocardiografia

Positive a preditivo value of an inquiry method is in such a way bigger the more narrow will be the existing relation enters the information for it offered and the fisiopatologia of the present illness. Perhaps this is the most important criterion to be considered how much of the use of an inquiry procedure. This 0 variable means the probability of occurrence of an event when determined found, on to the illness, it will be found in the complementary inquiry. Analyzed in another way, it means the probability of the individual to be really carrying of an illness, when the result of the test is positive. When positive the preditivo value is raised, the result of the inquiry method can be used to establish a therapeutical strategy with high probability of success. Of the opposite, when positive the preditivo value is low, it means that other factors, beyond that 0 variable that is being investigated, it influences the clinical evolution.

Dynamic Eletrocardiografia in the Stratification of Risk for Sudden Death the reason for which the 24-hour patients if submit to the Holter, when presents symptoms, is to clarify the origin of these and its possible relation with alterations of the cardiac rhythm.

When they present complex arrhythmias and they are assintomticos, is for identifying the individuals with worse prognostic and, with this, trying to improve the supervened one through an effective treatment. Some studies in literature have demonstrated that the presence of those arrhythmias, detected for the dynamic eletrocardiografia, after the acute phase of infarto of the myocardium is indicative of bad prognostic in the evolution in the near future. However, even so the especificidade and the negative preditivo value of such finding are raised, sensitivity and positive the preditivo value remains low. This perhaps if must to the proper characteristics of the involved populations in the studies or, then, that the arrhythmias they are only marking of high risk, not being involved directly in the death cause. .
