A comparison of T-wave alternans, signal averaged electrocardiography and programmed ventricular stimulation for arrhythmia risk stratification.
OBJECTIVES The goal of this study was to compare T-wave alternans (TWA), signal-averaged electrocardiography (SAECG) and programmed ventricular stimulation (EPS) for arrhythmia risk stratification in patients undergoing electrophysiology study. BACKGROUND Accurate identification of patients at increased risk for sustained ventricular arrhythmias is critical to prevent sudden cardiac death. T-...
متن کاملT wave alternans for ventricular arrhythmia risk stratification.
Sudden cardiac death remains one of the leading causes of death in Europe and the United States. Accordingly, the ability to identify patients at high risk of sudden cardiac death is important so that appropriate treatments can be used efficiently. Recently, T wave alternans (TWA) has emerged as a promising new test for such risk stratification. TWA is a heart rate dependent measure of arrhythm...
متن کاملMicrovolt T-wave alternans for risk stratification in athletes with ventricular arrhythmias: correlation with programmed ventricular stimulation.
BACKGROUND Aim of our study is to evaluate the role of T-wave alternans (TWA) to stratify the risk of sudden cardiac death in athletes (Ath) with complex ventricular arrhythmias (VA), and to document a possible correlation between TWA and electrophysiological testing (EPS) results. METHODS We studied 85 Ath with VA (61 M, mean age 32 +/- 11 years). In all cases a cardiological evaluation was ...
متن کاملT Wave Alternans And Ventricular Tachyarrhythmia Risk Stratification: A Review
Sudden cardiac death (SCD) is one of the leading causes of mortality in industrialized countries. Thus, identifying patients at high risk of SCD is an important goal. T wave alternans (TWA) is a new method for identifying patients with lethal ventricular tachyarrhythmias, and is dependent on heart rate. The maximal predictive accuracy is achieved at heart rates between 100 and 120 bpm, so that ...
متن کاملT-Wave alternans for arrhythmia risk stratification in patients with idiopathic dilated cardiomyopathy.
Identification of individuals at risk for life-threatening arrhythmias has proved to be challenging in patients with nonischemic heart disease in general and in those with idiopathic dilated cardiomyopathy (DCM) in particular. This is an important clinical problem, as DCM accounts for approximately 10% of all adult sudden cardiac deaths and has a one-year mortality of 10% to 50% (1,2). Most of ...
