查询词典 atrial

Pella R. The protective effect of atrial natriuretic peptide on cells damaged by oxygen radicals is mediated through elevated CGMP-levels, reduction of calcium-inflow and probably G-proteins.

心肌肥厚是细胞促增殖和抑增殖因素失去平衡的结果，以往的研究多集中于促增殖因子如ET-1、 AngⅡ等，但是从治疗的角度看，对抑增殖因子的研究具有更重要的意义。

Objective To study the morphogenesis of atrial septum and foramina secunda.

目的 探讨心脏房间隔与第二孔形态发生机制。

Methods Based on Hamburger and Hamilton staging, chick embryos were selected.The formation of atrial septun and foramina secunda were observed with microdissection and SEM.

METHODS: We performed AF substrate ablation guided by complex fractionated atrial electrogram mapping in 674 high-risk AF patients.

674名高风险AF患者在复杂分割的心房电图标测引导下进行AF消融。

Results For the hypertrophies in left or right atrium or ventricle or doule atriums or ventricles, the ECG plus VCG method had a high sensibility and accuracy.For the hypertrophies in right atrium and double atriums,the only ECG method had the same sensibility with the ECG plus VCG method.For the righ ventricle, the only VCG method had the same sensibility with the ECG plus VCG method.For the specificity, the three methods almost had the same value.ECG plus VCG method combining the clinical material could improve the acuracy in the diagnosis of atrial and ventricular hypertrophies.

结果：ECG和VCG联用对左心房、右心房、左心室、右心室、双心房、双心室肥大诊断的敏感性及准确性最高，ECG单独应用及ECG和VCG联用对右心房及双心房肥大的诊断敏感性相同，VCG单独应用和ECG和VCG联用对右心室肥大的诊断敏感性相同；3种方法对心房、心室肥大诊断的特异性相近；ECG和VCG联用诊断心房、心室肥大时结合临床资料可提高准确性。

Under the transmission electron microscope, we found adjacent cells in rat MSCs with mHCN4 gene and neonata atrial cells in coculture often had intimately apposed interdigitating cell membranes.

经检测mHCN4基因修饰大鼠MSCs可表达Cx43，其表达水平明显较GFP组及未转染组高，与心房肌细胞的Cx43表达水平无明显差异。

Atrial fibrillation, often called A-Fib, is the most common form of irregular heartbeat.

心房颤动，通常被称为一个纤维，是最常见的形式，心律不齐。
