Effects of biventricular pacing on right ventricular function assessed by standard echocardiography.
BACKGROUND AND AIM The aim of this study was to evaluate the short term effect of cardiac resynchronisation therapy (CRT) on right ventricular (RV) function assessed by standard echocardiography. METHODS Data from 57 patients (54 men, 95%; three women, 5%), aged 66.4 ± 8.7 years with heart failure (HF) was analysed. All patients were in NYHA III-IV functional classes, despite optimal pharmaco...
متن کاملAcute effects of biventricular pacing on right ventricular function assessed by tissue Doppler imaging.
AIMS The benefits of cardiac resynchronization therapy (CRT) on functional status, left ventricular (LV) remodelling and survival in patients with drug-refractory congestive heart failure (CHF), LV systolic dysfunction, and wide QRS have been demonstrated in randomized trials. However, the impact of CRT on right ventricular (RV) function, an independent prognostic factor in CHF remains question...
متن کاملEffect of right ventricular versus biventricular pacing on electrical remodeling in the normal heart.
BACKGROUND Biventricular (BIV) pacing can improve cardiac function in heart failure by altering the mechanical and electric substrates. We investigated the effect of BIV versus right ventricular (RV) pacing on the normal heart. METHODS AND RESULTS Male New Zealand White rabbits (n=33) were divided into 3 groups: sham-operated (control), RV pacing, and BIV pacing groups. Four weeks after surge...
متن کاملRight ventricular pacing for right ventricular outflow tract obstruction in a man with biventricular hypertrophic cardiomyopathy.
A 40-year-old man with known hypertrophic cardiomyopathy presented with syncope after coughing. Physical examination revealed a systolic murmur that was accentuated by the Valsalva maneuver. An electrocardiogram suggested biventricular hypertrophy and biatrial enlargement (Fig. 1). Echocardiograms revealed asymmetric septal hypertrophy with a diastolic septal thickness of 2.3 cm, and evidence o...

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
