Uncertainty 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...
متن کاملSignal averaged electrocardiography and renal function in hypertensive patients
Abnormal signal averaged electrocardiograms (SAECGs) and late ventricular potentials (LVPs) are predictors of sudden cardiac death. The present study hypothesized that SAECGs are impaired in hypertensive patients with renal failure. A total of 30 patients with grade 2 hypertension underwent SAECG. Serum level of creatinine and glomerular filtration rate (GFR) were also assessed. At least one SA...
متن کاملsignal-averaged electrocardiography in patients with advanced heart failure: a better indicator of left ventricular enlargement compared with conventional electrocardiography
background : the signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. the purpose of this study was to demonstrate the correlation between the filtered qrs duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes an...
متن کاملDIFFUSE CORONARY ARTERIAL ECTASIA WITH HYPERTROPHIC CARDIOMYOPATHY
A 40 year old male, a known case of hypertrophic cardiomyopathy, was admitted for catheterization. At catheterization and angiography, septum was hypertrophied to about 5cm and diffuse coronary artery aneurysm was revealed. We found no previous report of coronary artery aneurysm in hypertrophic cardiomyopathy.
متن کاملAbnormal Signal-Averaged Electrocardiogram in Patients With Nonischemic Congestive Cardiomyopathy
Background. An abnormal signal-averaged ECG (SAECG) has predictive value for arrhythmic events in patients with coronary artery disease. The purpose of this study was to investigate whether an abnormal SAECG could provide prognostic information in patients with nonischemic dilated cardiomyopathy. Methods and Results. We prospectively obtained SAECGs in 114 patients with dilated nonischemic card...
