导管射频消融治疗老年人阵发性室上性心动过速

Characteristics of radiofrequency current catheterablation in the treatment of elderly patientswith supraventricular tachycardia

对５３例老年阵发性室上性心动过速（ＰＶＳＴ）患者进行心内电生理检查及导管射频消融（ＲＦＣＡ），其中房室结内折返性心动过速２６例，房室旁路所致房室折返性心动过速２７例；２１例合并有高血压、冠心病等，其中５例为病窦综合征。全部病例一次消融成功，无并发症。结果表明ＲＦＣＡ是治疗老年人ＰＶＳＴ安全有效的措施。

To study the effects and characteristics of radiofrequency current catheter ablation (RFCA) in treatment of elderly patients with supraventricular tachycardia (PSVT), fiftythree elderly patients and fifty nonelderly patients with PSVT were included in this study. RFCA were performed in both groups. The group of elderly patients included 26 patients with atrioventricular nodal reentrant tachycardia and 27 patients with atrioventricular reentrant tachycardia due to 29 atrioventricular accessory pathways (Aps). Twentyone patients were accompanied with hypertension and coronary heart diseases and 5 sick sinus syndrome cases in the elderly group. All patients in both groups were treated successfully with RFCA. The procedure time of ablation of slow pathway in elderly group was shorter than that of the nonelderly group (P<0.01). A mild symptom of arterial thrombosis was found in 2 cases of the elderly group after treatment and was cured with aspirin. These results suggest that PFCA is very effective and safe in the treatment of elderly patients with PSVT, especially for patients accompanied with sick sinus syndrome.
