Ventricular arrhythmias and sudden cardiac death

Abstract

Sudden cardiac death (SCD) - this natural death caused by cardiac reasons and which is characterized by sudden loss of consciousness within first hour after revealing of sharp clinical symptoms. A primary factor of SCD is not traumatic. It occurs suddenly and unexpectedly. The high risk of development of sudden cardiac death is basically associated with ventricular arrhythmias. Electrophysiological anomalies in cells lead to development of ventricular ectopic activity or ventricular tachycardia which comes to the end with fibrillation. The ultimate goal of antiarrhythmic drug therapy is to restore normal rhythm and conduction Treatment of ventricular arrhythmia provides application of antiarrhythmic medicines, beta-adrenoblokators, amiodarone, lidocaine, sotalole, implantation cardioverters - defibrillators (ID), catheter ablation, surgical manipulations. ID therapy is recommended for primary prevention developments SCD in patients with ventricular fibrillation against a background of the acute miocardial infarction.
