心房停顿大多发生在心房颤动的药物治疗过程中,例如用洋地黄或奎尼丁。持久心房停顿也可见于许多结构性病变,包括肌营养不良、家族性淀粉样变性、Chagas 病和病因不明的心房退行性疾病,其特点是心房不能应激。由高钾、系统性红斑狼疮、白喉、心肌梗塞和心内手术引起的暂时性心房停顿可有不等程度的心房应激性抑低。本文报告3例暂时性心房停顿患者,经电生理检查证明心房激动完整,提示系同时具有窦房结疾病、室房传导障碍和心房异位搏动灶的抑制。
Atrial pause mostly occurs during pharmacotherapy of atrial fibrillation, such as digitalis or quinidine. Long-term atrial pause can also be seen in many structural diseases, including muscular dystrophy, familial amyloidosis, Chagas disease and an unknown etiologic atrial degenerative disease characterized by atrial inability to stress. Temporary atrial pause caused by high potassium, systemic lupus erythematosus, diphtheria, myocardial infarction and intracardiac surgery may have varying degrees of atrial stress depression. This article reports 3 cases of temporary atrial pause patients, electrophysiological examination showed that atrial activation is complete, suggesting that the system has both sinus node disease, conduction disturbance of the room and atrial ectopic pulsatile suppression.
