متن کاملPredictive value of T-wave alternans for arrhythmic events in patients with congestive heart failure.
Measurement of microvolt level T-wave alternans in the surface electrocardiogram is a novel way to assess the risk of ventricular arrhythmias. Seven tests of arrhythmic risk, including T-wave alternans, were undertaken in 107 consecutive patients with congestive heart failure and no history of sustained ventricular arrhythmias; the patients were followed up for arrhythmic events during the next...
متن کاملMultiple autonomic and repolarization investigation of sudden cardiac death in dilated cardiomyopathy and controls.
BACKGROUND Prophylactic defibrillator implantation is recommended in dilated, nonischemic heart disease and left ventricular ejection fraction of ≤0.30 to 0.35. Noninvasive testing should improve accuracy in decision making of prophylactic defibrillator implantation. METHODS AND RESULTS We enrolled 60 patients (median age, 57 years) with dilated cardiomyopathy and left ventricular ejection fr...
متن کاملT-wave alternans and sudden cardiac death.
Sudden cardiac death (SCD) is the leading cause of mortality in patients with ischemic heart disease and left ventricular dysfunction. The majority of SCD are due to ventricular tachyarrhythmias. SCD strikes many asymptomatic patients and often is the first manifestation of heart disease. Thus, reliable determination of arrhythmic risk is warranted to guide preventive therapy. To highlight the ...
متن کاملicrovolt T-Wave Alternans for the Risk tratification of Ventricular Tachyarrhythmic Events
OBJECTIVES The objective of this study was to perform a meta-analysis of the predictive value of microvolt T-wave alternans (MTWA) testing for arrhythmic events in a wide variety of populations. BACKGROUND Previous studies describing the use of MTWA as a predictor of ventricular tachyarrhythmic events have been limited by small sample sizes and disparate populations. METHODS Prospective studies...
