心动过速的

After implanted the physiological pacemakers, the cerebral ischemic symptoms of the patients including amaurosis, syncope, swirl and so on disappeared, cardiac dysfunction and the exercise capacity improved. No pacing syndrome and no pacemaker intervened tachycardia was observed.

DDD起搏器植入术后患者脑血管缺血症状全部消失，心功能不全明显改善，运动耐量也明显提高，无起搏器综合征、起搏器介导的心动过速的发生。

BACKGROUND: In some types of pediatric supraventricular tachycardia,reentrant mechanisms are sensitive to enhanced vagal tone.

背景：在小儿室上性心动过速的一些类型中，折返机制对增高的迷走神经张力很敏感。

If this changes appear in any part of the reentrant circle, reentry will be interrupted due to the loss of match.

如这一改变出现在折返性心动过速的折返环路上的任何部位即可因传导时间和不应期的失匹配而使折返运动终止。

Objective To analyze the occurrence, ECG characteristics of non-standing ventricular tachycardia and its clinical significance.

目的 分析非持续性室性心动过速的发生、心电图特点及其与临床的关系。

Transmembrane action potentials were recorded simultaneously from endocardium, epicardium, together with a transmural ECG, in arterially perfused left ventricular preparations by use of 2 separate intracellular floating microelectrodes. The stimulus-response- interval of the epicardium and the incidence of ventricular tachycardia were observed as well.

灌流全程同时采用浮置玻璃微电极法同步记录内膜下心肌、外膜下心肌跨膜动作电位和跨壁ECG，并观察心外膜下心肌的刺激反应间期(Stimulus-response-interval， SRI)和室性心动过速的诱发率。

Objective To explore the accuracy of differential diagnosis of paroxysmal supraventricular tachycardia and locating diagnosis of by-pass done by vectorcardiogram.

目的 探讨心电向量图对阵发性室上性心动过速的鉴别诊断及旁路定位诊断的准确性。

Objective To explore the values of ST segment elevation in lead aVR for differentiating paroxysmal supraventricular tachycardia.

目的探讨aVR导联ST段抬高及其持续时间对阵发性室上性心动过速的鉴别价值。

Supraventricular or ventricular tachycardia is most often perceived as being rapid and regular and of sudden o et and termination.

室上性或室性心动过速的感觉是快速、有规律，来去突然。

Objective: To observe conversion rates for paroxysmal supraventricular tachycardia with adenosine.

目的：采用随机、双盲、平行对照多中心试验方法评价国产腺苷注射液治疗阵发性室上性心动过速的临床疗效和安全性。

This structural change may result in a substrate that can support a wider spectrum of re-entrant ATs, which may co-exist in the same period.

出现更多再发性房性心动过速的基础可能是这种结构改变产生的，并且在同一时期内这种改变共存。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
