1·Objective: To explore the clinical feature and cause of paroxysmal atrial tachycardia .

目的：探讨短阵房性心动过速的临床特点和发生原因。

2·Objective To investigate the mechanism of atrial tachycardia and the results of radiofrequency ablation.

目的探讨房性心动过速的发生机制和射频消融结果。

3·Recurrent atrial tachycardia and atrial fibrillation after circumferential pulmonary vein ablation: What's the difference?

复发性房性心动过速，后环肺静脉消融房颤：有什么区别？

4·In the Bronx Longitudinal Aging Study, the occurrence rate of paroxysmal atrial tachycardia is 13% at aged 75 to 85 years old.

老年人房速的发生率较高，75 ~ 85岁老年人中阵发性房速的发生率为13%。

5·Results The clinical attack pattern of atrial tachycardia was very similar to that of repetitive monomorphic ventricular tachycardia.

结果反复单形房速的发作方式与反复单形室性心动过速相似。

6·Catheter ablation of atypical atrial flutter and atrial tachycardia within the coronary sinus after left atrial ablation for atrial fibrillation.

经冠状窦内消融治疗左房消融治疗心房颤动术后患者的典型心房扑动和房性心律失常。

7·Asymptomatic paroxysmal atrial tachycardia (PAT) was tested in 1128 cases of heart disease by 24-hour ambulatory electrocardiography, and was discovered in 279 cases, examination rate is 24.7%.

应用24小时动态心电图观察以心脏病为主的连续1128例病人，发现无症状短程阵发性房性心动过速(PAT)共279例，检出率24.7%。

8·During a mean follow-up of 19 months, 14 patients (56%) remained in stable sinus rhythm, and 11 patients (44%) experienced recurrence of paroxysmal AF, permanent AF, or left atrial tachycardia.

在19个月的平均随访期内，14名患者(56%)继续保持稳定的窦性心律，而11名患者(44%)出现阵发性AF、永久性AF或左心房房速复发。

9·Heart failure. This can result if your heart is pumping ineffectively for a prolonged period due to a bradycardia or tachycardia, such as atrial fibrillation.

心衰持续的心率失常(比如房颤)会使心脏在很长时间里无法有效地泵血，从而引起心衰。

10·Dysrhythmias, including unexplained tachycardia, atrial fibrillation, premature ventricular contractions, and ST segment changes, may indicate blunt cardiac injury.

节律异常，包括难以解释的心动过速、房颤、室早和ST段改变，都提示心脏钝性伤的可能。
