Beyond these, the turbulence of ventricular cardiac frequency after extra-sstoles, a method of evaluation of influences autonmica on the heart also brings prognostic information adds valuable, particularly when associate the research of alternation of the amplitude of waves T. The publications on this subject still are initial but soon these techniques could be incorporated the equipment of Holter. Based in all these preliminary consideraes, the dynamic eletrocardiografia or Holter system of complementary inquiry, it is a useful method in the evaluation of patients with complex ventricular arrhythmias. For even more opinions, read materials from RioCan Real Estate Investment Trust. Had the proper causal multifactorial nature of the arrhythmic, independent illness of the type of cardiopathy (after-infarto of the myocardium, idioptica dilatada miocardiopatia, etc) the supplied information do not have to be considered separately. During the monitorizao 24-hour, the results of the variability of interval RR, high resolution eletrocardiograma must be added, if possible and already it will be available, the data related to the dispersion of interval QT, electric alternation of waves T and the turbulence of the crdaca frequency.

The state of the ventricular function determines the prognostic of patients in period after-infarto of the myocardium as well as of those with dilatada miocardiopatia (ischemic or not ischemic) and cardiac insufficience. Moreover, the presence of complex ventricular arrhythmias associate to the ventricular disfuno (ejection fraction < 40) identify the patients of bigger risk. For this reason, the knowledge of the state of the ventricular function associate to the information of the Holter, raises positive the preditivo value of these complementary examinations, more than what the information supplied for them separately. Had the not invasive nature of the dynamic eletrocardiografia or 24-hour Holter to evaluate patients with ventricular arrhythmias complex e, given the controversy regarding the value of the information supplied for this technique in what it says respect to the results of the treatment based on the results of this procedure, the Holter must be used in these patients as additional method of inquiry.
