心动过速的

Tachycardia: abnormally rapid heart rate, 160 to 190 beats per minute.

心动过速：异乎寻常的快速心率， 160至190次每分钟。

Objective:To explore the significance of ST-segment depression during paroxysmal supraventricular tachycardia in the diagnosis of coronary heart disease.

目的：探讨阵发性室上性心动过速时ST段压低对冠心病的诊断价值。

Levofloxacin prolongs cardiac repolarization, a factor that is known to predispose to Torsade de Pointe, much more than moxifloxacin.

左氧氟沙星延长心脏的复极化，事实是都知道它可以预先用来治疗变异室性心动过速，要好过莫西沙星很多。

Ventricular tachycardia or fibrillation or severe bradycardias or asystole may cause these symptoms in the form of a Stokes-Adams attack.

室性心动过速及心室纤颤或严重的心搏除缓或心搏停止均可引起这些症状，表现为Strokes-Adams发作。

Methods:We ablated the ventricular tachycardia of 12 patients with normal hearts by the catheter, using pace mapping and activation sequence mapping. The former original target was the site where the pacing QRS was entirely consistent with IVT(Idiopathetic Ventricular Tachycardia) attack. And the latter original target was the site of in advance of earliest high frequency and low amplitude local potential on surface electrocardiogram QRS≥20ms, using activation sequence mapping. Results: Among 12 patients, the IVT originated from right ventricle in 2 patients, from left ventricle in 10 patients.

对12例正常心脏室速进行导管消融，采用起搏标测与激动顺序标测，前者以起搏时与室速QRS波型形态完全相同，后者以激动顺序标测法定位，以记录心动过速时较体表心电图QRS提前≥20ms的最早高频低振幅局部电位处为消融靶点，结果：12例患者室速起源部位分别为：右心室2例，左心室10例，疗效100%。

This finding is helpful for the promptly distinguisgment of orthodromic AVRT using a concealed accessory pathway.

这有助于及时识别窄QRS波心动过速AVRT，尤其是右侧隐匿性旁路参与的AVRT。

The most common is Paroxysmal Supraventricular Tachycardia.

最常见的是阵发性室上性心动过速。

Methods: The transesophageal atrial pacing and electrophysiologic study were performed in 237 patients with history of tachycardia, if PSVT was induced, the patients received overdrive suppression or program prestimulation.

选择237例有心动过速发作史的患者进行食管心房调搏检查，如果诱发出阵发性室上速，进行12导联心电图记录后，予以短阵快速刺激或程序期前刺激终止之。
