心动过速的

A new hypothesis is proposed that it may be possible to selectively ablate retrograde fast pathway to cure typical atrioventricular nodal reentrant tachycardia.

设计一种新的射频消融方法对25例反复发作的典型房室结折返性心动过速进行消融治疗。

The discovery of the Bainbridge reflex 70 years ago, of a tachycardic response to a rise in central venous pressure, stimulated a lot of interest in this and other cardiovascular reflexes.

Bainbridge reflex发现于70年前，指中心静脉压力的增高导致心动过速，当时引起了人们对此以及其他心脏血管反射的兴趣。

The result indicated that HSC could obviously cut down the occurrence of rentricular vibration induced by chloroform in mice,lengthen the time of arrhythmia appearance,shorten the time of arrhythmia continuum and conversion induced by barium chloride in model rats,it also could shorten the time of ventriclar extrasystole and ventricular tachycardia in model rats induced by aconitine.

结果表明：黄松胶囊能明显降低氯仿所诱发小鼠室颤的发生，明显延长氯化钡模型大鼠心律失常出现时间，缩短模型大鼠心律失常持续和复律时间，尚能明显缩短乌头碱性大鼠心律失常的室性早搏及室性心动过速持续时间，与模型对照组比较均有统计学差异。

Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.

将实验动物随机分为生理盐水组，阳性药物对照组，藏红花酸高、中、低剂量组，SD大鼠采用1.2 g/kg乌拉坦麻醉后，从尾静脉匀速(0.1 ml/min)灌注10μg/ml乌头碱溶液，豚鼠麻醉后从颈静脉匀速(0.1 ml/min)灌注9μg/ml哇巴因溶液，观察出现室性期前收缩、室性心动过速、室颤和心脏停搏的时间，然后换算成乌头碱和哇巴因的累积量；快速推注4%氯化钙(140 mg/kg)诱导大鼠心律失常，观察给药后心律失常出现时间、持续时间、心律失常发生数及死亡数。

Objective:To cure the refractory supraventricular tachycardia associated with Ebstein?s anomaly.

目的：为治疗伴发于Ebstein畸形的阵发性室上性心动过速，我们对4例患者进行了射频导管消融。

Objective:[WT5BZ]To discuss the security and efficacy of radiofrequency catheter ablation treating paroxysmal supraventricular tachycardia.

目的 ：经导管射频消融治疗阵发性室上性心动过速 2 6 2例，探讨RFCA治疗 PSVT的安全性及疗效。

However, many of the classic signs and symptoms of deep-veinthrombosis and pulmonary embolism, including leg swelling, tachycardia,tachypnea, and dyspnea, may be associated with a normal pregnancy.

然而，深静脉血栓形成和肺栓塞的很多典型症状和体征，包括腿部肿胀、心动过速、呼吸过快和呼吸困难，很可能与一次正常妊娠有关。

Droperidol, a potent anti-emetic, has fallen into disfavor because of its association with QT prolongation and torsades de pointes.

达哌啶醇是一种有效的抗呕吐药物，因为QT间期延长及尖端扭转型室性心动过速有关已经不被赞成使用。

None of them had pre-excitation in sinus rhythm.

观察并测量全部窄QRS波心动过速发作时Ⅱ、Ⅲ和aVF导联ST段压低/T波倒置的幅度。

The myocardial image of 23 cases of ventricular premature beat was performed by the velocity mode of the DTI meanwhile ECG could be used.

发现当心电图上出现室性早搏或短阵室性心动过速时，DTI可同步显示早搏起源部收缩期高于其它部位心室肌运动的某一黄色亮点区，平均速度可达0.10～0.21m／s。
