Echocardiographic Assessment of Left Ventricle Torsion by Tissue Doppler and Velocity Vector Imaging
Introduction Left ventricular (LV) twist is believed to store potential energy and plays an important role in generating diastolic suction. Recent advances in echocardiography techniques have allowed quantification of LV twist. The aim of the present study was to compare LV twist and torsion in healthy human subjects determined by velocity vector imaging (VVI) and tissue Doppler imaging (TDI) a...
متن کاملIdentification of fetal atrial flutter by Doppler tissue imaging.
A26-year-old woman presented at 33 weeks of gestation with a singleton fetus with tachycardia. A complete fetal echocardiogram revealed a structurally normal fetal heart without signs of hydrops. The fetal heart rate was between 200 and 220 bpm. Evaluation of the rhythm with pulsed Doppler and M-mode scanning was not definitive. Fetal Doppler tissue imaging color M-mode scanning was performed b...
متن کاملCharacterization of ventricular myocardial performance in the fetus by tissue Doppler imaging.
BACKGROUND Clinically useful indices of fetal cardiac function have not been fully delineated for tissue Doppler imaging (TDI). METHODS AND RESULTS In the present study, 56 pregnancies between the 17(th) and 38(th) weeks of gestation included 38 normal fetuses, 6 cases of hydrops fetalis (HF), and 12 of intrauterine growth retardation (IUGR). Peak velocity in early diastole (E) was measured b...
متن کاملAssessment of left ventricular systolic and diastolic function by tissue Doppler imaging after acute myocardial infarction.
OBJECTIVE To evaluate left ventricular systolic and diastolic function by Tissue Doppler imaging after acute myocardial infarction. METHODS It was a hospital based, prospective descriptive study, from 1st July 2010 to 31st Dec. 2010. Total of 200 patients having acute myocardial infarction underwent detailed tissue Doppler imaging (TDI) echocardiographic examination for evaluation of left ven...

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
