SUDDEN DEATH PREDICTORS IN PATIENTS AFTER MYOCARDIAL INFARCTION BY HOLTER ECG MONITORING

Abstract

The recent data is considered on the prevalence, electrophysiology, mechanisms and risk factors of sudden cardiac death in patients after acute myocardial infarction. The data is shown about Holter monitoring of ECG as a method (these methods are in use in systems like Astrocard® Holtersystem, GE Healthcare MARS, medilog® DARWIN), that stratifies the risk of sudden cardiac death development. The prognostic role and importance of specific parameters of 24-hour ECG monitoring is studied, correlating with the higher risk of life-threatening rhythm disorders that are the main mechanisms of sudden cardiac death. The estimation of the main predictors of electrical instability of myocardium is done.
