Abstract:
In many cases ventricular arrhythmia is the first in the gradual transformation of sudden cardiac death, but also a manifestation of fatal heart disease, so the main focus of studies in recent years World Cardiology is the search for markers of risk and ways to effectively prevent sudden cardiac death (SCD). Well studied electrocardiographic parameters which, are registered at Holter monitoring, such as the number, grading and ventricular morphology ectopias, fluctuations in the length of the QT interval are useful predictors of high risk in deciding on the expediency of primary prevention through RSD cardioverter-defibrillator implant or antiarrhythmic therapy. Existing today the selection criteria for primary prevention of sudden cardiac death of insufficient effective. Study on ECG measurements which are closely associated with ventricular ectopias, analysis of their relationship with the autonomic regulation provides the basis for new methods of diagnosis and treatment of risk-stratified markers. Physician should consider the state of the autonomic regulation of cardiac activity, when he choose the means of antiarrhythmics drugs, for its evaluation recently widely used spectral analysis and the variability of heart rate turbulence.
