Background and Aim: Smoking stimulates adrenergic depletion in circulation and, theoretically, it can increase incidence and prevalence of cardiac conduction defects. In this study we wanted to know if smoking affected cardiac conduction defects in patients with acute inferior myocardial infarction (MI). Materials and Methods: In this cross- sectional study, 40 smokers and 40 non – smokers wit...
abstract the present study was conducted in order to investigate the impact of an integrated model of form-focused and task-based instruction on iranian efl learners vocabulary learning and retention.it also aimed to detect efl learners attitude towards the implementation of form-focused task-based vocabulary instruction in the classroom. in order to address the purposes of this study, a sampl...
هدف از انجام این پروژه در ابتدا سعی در معرفی و رسیدن به اصل روش حجم کنترل بر مبنای روش المان محدود (control volume based finite element method) و سپس ارائه یک الگوریتم برای حل یک مسئله انتقال حرارت رسانایی (conduction type problem) در یک هندسه پیچیده توسط این روش و پس از آن نیز ارائه برنامه ای جهت اجرا در رایانه بر مبنای این الگوریتم می باشد. روش حجم کنترل بر مبنای روش المان محدود یا اختصار cvb...
ABSTRACT The object of this study is determination of normative values of nerve conduction studies (NCS) among the population of Guilan Province. We selected 216 at the ages of 20-59yr on the basis of their medical histories and examination , and on condition that they had no factors or diseases interfering with nerve conduction by convenience sampling method. In this cross-sectional study, t...
CONCEALED CONDUCTION in the atrioventricular (AV) junction in association with coordinated atrial activity is a well-recognized phenomenon,1-3 recently confirmed with new technics in animal experiments.4-6 Its operation in atrial fibrillation has received less attention, although it appears to offer the best explanation for the characteristic irregularity of the ventricular responses.7 11 It is...

This paper presents a method of using volume conduction for communication with implanted passive RFID tags. Based on electrode coupling, this method uses mainly electric field to transmit signal through tissue, and therefore can reduce the interference with metallic implants when RFID tags are attached to the implants. Exterior and interior electrodes are designed for efficient energy and signa...
Enhanced AAIR7DDDR pacing (atrial-based Managed Ventricular Pacing [MVP]) is a novel pacing mode that facilitates intrinsic conduction whenever possible to mitigate the deleterious effects of prolonged duration right ventricular (RV) electric stimulation on left ventricular contractility. The following case illustrates uncommon ECG and hemodynamic consequences of this algorithm in a patient wit...
