Effect of haemodialysis on signal-averaged electrocardiogram P-wave parameters.
BACKGROUND The P-wave signal-averaged electrocardiogram (SAECG) is a non-invasive technique considered to indicate an increased risk for paroxysmal atrial fibrillation. The study was designed to evaluate the effect of the haemodialysis (HD) process on SAECG parameters in the group of selected HD patients. METHODS Forty-seven HD patients (without relevant cardiac diseases) were included. SAECG...
متن کاملDetection of patients at risk for paroxysmal atrial fibrillation during sinus rhythm by P wave-triggered signal-averaged electrocardiogram.
To determine whether patients at risk for paroxysmal atrial fibrillation could be detected while in sinus rhythm, the signal-averaged electrocardiogram triggered by P waves was recorded in 42 patients with paroxysmal atrial fibrillation (Paf group) and in 50 control patients. The root mean square voltages (LP10, LP20, and LP30) for the last 10, 20, and 30 msec and the duration (Ad) of filtered ...
متن کاملPredictive value of wavelet decomposition of the signal-averaged electrocardiogram in idiopathic dilated cardiomyopathy.
BACKGROUND Wavelet decomposition of the signal-averaged electrocardiogram has been proposed as a method of detecting small and transient irregularities hidden within the QRS complex and of overcoming some of the limitations of time domain analysis of the signal-averaged electrocardiogram. AIM This study evaluated the potential utility of wavelet decomposition analysis in the risk stratificati...

ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...
Effect of Hypertension on the P Wave of the Electrocardiogram.
The P wave of the electrocardiogram has been investigated in great detail in normal subjects (Shipley and Hallaran, 1936; Graybiel et al., 1944; Stewart and Manning, 1944; Thomas and Dejong, 1954) and in various types of cardiac disease (Wood and Selzer, 1939; Thomas and Dejong, 1954; Martins de Oliveira and Zimmerman, 1959). There have been few studies of the P wave in hypertension, however, a...
