Prediction and stratification of the future cardiovascular arrhythmic events: signal averaged electrocardiography versus ejection fraction.
Cardiac arrhythmias as cause of sudden cardiac death remains an important public health problem. The availability of effective treatment in terms of the implantable defibrillator makes it critical to identify individuals at risk. An essential step in this process is the use of noninvasive techniques to screen patients and identify those at risk. The detection of ventricular late potential using...
متن کاملRight Ventricular Ejection Fraction Is Incremental to Left Ventricular Ejection Fraction for the Prediction of Future Arrhythmic Events in Patients With Systolic Dysfunction
Current American College of Cardiology/American Heart Association/Heart Rhythm Society guidelines recommend the use of left ventricular ejection fraction (LVEF) to inform therapeutic decision making about implantable cardioverter defibrillator (ICD) therapy. However, of patients receiving devices in accordance with published LVEF-based thresholds, only a minority (21–35%) receive appropriate th...
متن کاملRight Ventricular Ejection Fraction Is Incremental to Left Ventricular Ejection Fraction for the Prediction of Future Arrhythmic Events in Patients With Systolic Dysfunction.
BACKGROUND Left ventricular ejection fraction remains the primary risk stratification tool used in the selection of patients for implantable cardioverter defibrillator therapy. However, this solitary marker fails to identify a substantial portion of patients experiencing sudden cardiac arrest. In this study, we examined the incremental value of considering right ventricular ejection fraction fo...
متن کاملUncertainty principle of signal-averaged electrocardiography.
BACKGROUND Signal-averaged ECG (SAECG) reproducibility is reported to have a component that is independent of residual noise. Methods and Results-In group 1, multiple paired SAECGs were obtained to noise levels of 0.3+/-0.1 and 0.5+/-0.2 microV. For the 0.5- and 0. 3-microV noise recordings, QRS duration (QRSd) was 101.2+/-11.3 and 104.6+/-9.6 ms, respectively (P<0.0001), and the differences in...
