查询词典 ostial

(1) The prevalence of atherosclerotic renal artery stenosis is 19.04% in a patient population undergoing cardiac catheterization, RAS is more commom in the ostial sites.

在中老年疑诊或诊断冠心病行动脉造影患者中，ARAs的发生率为19.04%，其狭窄部位多见于肾动脉开口处。

Circumferential pulmonary vein ostial isolation guided by EnSite NavX three-dimensional electrophysiological mapping can be effective and safe for AF treatment.

EnSite NavX三维电生理系统指导下环肺静脉前庭隔离导管消融治疗房颤是一种较为有效且安全的方法。

In addition, fractures were more common with ostial location, longer lesions, angulation, proximal tortuosity, extensive vessel calcification and total occlusion.

此外，支架断裂在开口病变、长病变、成角病变近段、扭曲病变、广泛钙化病变以及完全闭塞病变更为常见。

Off-label use was defined as use in restenotic lesions, lesions in a bypass graft, left main coronary artery disease, or ostial, bifurcated, or totally occluded lesions, as well as use in patients with a reference-vessel diameter of less than 2.5 mm or greater than 3.75 mm or a lesion length of more than 30 mm.

非适应症应用定义为支架应用于再狭窄病变、旁路移植血管病变、左主干病变、开口病变、分叉病变、完全性闭塞病变以及支架应用于靶血管参考直径小于2.5mm或大于3.75mm或病变长度大于30mm的患者。

Like MRA, CTA is useful when carotid duplex is ambiguous, permitting isualization of aortic arch or high bifurcation pathology, reliable differentiation of total and subtotal occlusion, assessment of ostial and tandem

CTA能够使主动脉弓和高位颈动脉分叉显影，可靠区分全部和部分血管闭塞，评估开口和串联性狭窄，而且能够对心律不齐，瓣膜性心脏病，心肌病患者的颈动脉疾病进行评价。

Sustained AF could be induced easily in all dogs during vagal nerve stimulation in vivo both before and after isolation of all PVs with encircling lesions created by a bipolar radiofrequency ablation clamp device. PV elimination had no effect on atrial effective refractory period or its responses to cholinergic stimulation. Autonomic ganglia were identified by bradycardic and/or tachycardic responses to high-frequency subthreshold local stimulation. Ablation of the autonomic ganglia overlying all PV ostia suppressed the effective refractory period-abbreviating and AF-promoting effects of cervical vagal stimulation, whereas ablation of only left- or right-sided PV ostial ganglia failed to suppress AF.

无论是在双极环状消融所有PV之前或之后，在体刺激颈迷走神经节过程中持续性房颤在所有犬均能轻易被诱导出，PV切除对心房肌的有效不应期或对胆碱的反应均没有影响，通过对高频的域下刺激发生快速或慢速反应来鉴定自主神经节，消融叠加于PV口部的自主神经节能抑制有效不应期的缩短、和刺激颈迷走神经诱发的房颤促进作用，而仅消融左或右侧PV口部的自主神经节却不能抑制房颤。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
