Clinical Significance of P Wave Dispersion in Prediction of Atrial Fibrillation in Patients with Acute Myocardial Infarction

Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) in 12-leads of the surface electrocardiography. The aim of this study was to evaluate the values of PWD during atrial fibrillation (AF) after acute myocardial infarction (AMI). Methods: We prospectively evaluated atrial rhythms of 350 patients (251 m...

Physicians' and Clinical Coders' Knowledge about Cause of Death Rules for Death Certification in Hospitals Affiliated to Kashan University of Medical Sciences

Introduction: To clarify mortality trend, enhancing the knowledge of physicians and clinical coders who play their role in coding based on ICD book is crucial. This study was performed to investigate the knowledge of physicians and clinical coders on the rules and guidelines of determining mortality causes. Methods: This descriptive cross-sectional study was performed on 152 health care provid...

Prediction of chronic kidney disease in Isfahan with extracting association rules using data mining techniques

Background: Millions of deaths occur around the world each year due to lack of access to appropriate treatment for chronic kidney disease patients. Given the importance and mortality rate of this disease, early and low-cost prediction is very important. The researchers intend to identify chronic kidney disease through the optimal combination of techniques used in different stages of data mining...

Prediction of Gas Hydrate Forming Pressures by Using PR Equation of State and Different Mixing Rules

Prediction of Vapor-Liquid Equilibria Using CEOS /GE Models

The present study investigates the use of different GE mixing rules in cubic equations of state for prediction of phase behavior of multicomponent hydrocarbon systems. To predict VLE data in multicomponent symmetric and asymmetric mixtures such as systems that contain light gases (nitrogen, carbon dioxide, etc.) and heavy hydrocarbons, the SRK equation of state has been combined with excess Gib...
