P-wave signal averaging. High tech or an expensive alternative to the standard ECG?
A trial fibrillation is the most common sustained arrhythmia treated by cardiologists and inter-nists, occurring in 0.4% of the general population and in 2% to 4% of those over age 60 years.1'2 Several small studies of coronary artery bypass grafting (CABG) have shown an incidence of postoperative atrial fibrillation ranging from 5% to as high as 40%. Recent large studies by Taylor et a12 and F...
متن کاملA New Method for Signal and Image Analysis: The Square Wave Method
A brief review is provided of the use of the Square Wave Method (SWM) in the field of signal and image analysis and it is specified how results thus obtained are expressed using the Square Wave Transform (SWT), in the frequency domain. To illustrate the new approach introduced in this field, the results of two cases are analyzed: a) a sequence of samples (that is, measured values) of an electro...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولP wave signal-averaged electrocardiogram as a new marker for atrial tachyarrhythmias in postoperative Fontan patients.
OBJECTIVES This study was undertaken to determine the potential role of P wave signal-averaged electrocardiogram (PSAECG) for risk assessment of atrial tachyarrhythmias (ATs) in patients after Fontan operation. BACKGROUND Onset of atrial flutter/fibrillation (AFF) in patients who have undergone Fontan operation for univentricular hearts constitutes an unfavorable clinical event associated wit...
متن کاملA New Method for Nonorthogonal Signal Decomposition1
ing with finite dimensional Gabor sets. Here we describe an iterative method which allows us to perform the decomposition for finite dimensional nonorthogonal sets including Gabor sets. The method is optimal and always stable in the sense that the minimum mean squared error, that is, the norm of the difference between the original function and the reconstructed one, obtained by this method tend...
