房间隔膨胀瘤伴多源性房性心动过速射频消融治疗1例

Ablation of multifocal atrial tachycardia in a patient with atrial septal aneurysm

房间隔膨胀瘤（atrial septal aneurysm,ASA）是由于先天性房间隔发育薄弱,在心脏负荷因素的作用下向低压侧膨隆而形成的瘤样膨出。研究发现,ASA的存在促进房性心律失常的发生[1-3]。本文报道1例ASA伴多源性房性心动过速（房速）成功射频消融治疗病例。1病例资料患者,男,20岁,3年来反复发作性心悸,多于劳累或情绪激动时发作,每次持续数分钟自行缓解。两个多月来心悸加重,每次持续数小时,本次入院前3d起呈持续发作,时轻时重,重时伴头昏、视物模糊。

The 20-year-old man suffered from paroxysmal palpitation in the last three years with multifocal atrial tachycardia associated to atrial septal aneurysm.The multifocal atrial tachycardia was cured successfully by radiofrequency ablation.
