accessory pathway tachycardia的用法和样例：
- Objective To observe the roles of ST segment elevation in lead aVR during tachycardia in differentiating the narrow QRS complex tachycardia and locating the accessory pathway.
- ST segment elevation in lead aVR has important values in differentiating AVRT with AVNRT and preliminarily locating the accessory pathway of narrow QRS complex tachycardia.
- AVRT showed tachycardia termination antegradely in the AV node in 12 patients (12/14 or 86%) and in 2 patients (2/14 or 14%) retrogradely in the accessory pathway.
14例AVRT患者静注腺苷后 ,14例均恢复窦性心律 ,终止AVRT 12例于房室结前传 ,2例于旁道逆传。
- Patients with preexcitation syndrome were susceptible to arrhythmia,and it was most usual in supraventricular tachycardia with accessory pathway (Kent).
