窦房病即窦房结功能障碍而无其他心脏病,其病因常不清楚。窦房病在年长者比年青者多见,年长患者可能伴有其他疾病如冠状动脉粥样硬化,而掩盖了窦房病的根本原因。儿童和青少年不会有这种附加疾病,因此,年青的窦房病患者是研究窦房病病因学最好的对象。对象和方法:9名年龄小于25岁的窦房病患者均有短暂的停搏所致的晕厥或头昏,且休息或动态心电图证实有窦房结功能障碍。本文中窦房结功能障碍系指白昼窦性心动过缓小于40次/分,心房停搏大于2.25秒或阵发性房性心动过速。除远端传导异常之外,其他心脏病均予剔除。9名患者均测量
Sinus disease that is sinus node dysfunction without other heart disease, the etiology is not clear. Siberian atrial fibrillation is more common in the elderly than in the elderly. Older patients may have other diseases such as coronary atherosclerosis, masking the underlying cause of sinoatrial disease. Children and adolescents will not have this additional disease, therefore, young patients with sinus disease is the best study of etiology of sinoatrial disease. Subjects and Methods: Nine patients with sino-atrial disease less than 25 years old had syncope or dizziness caused by short-term arrest, and resting or ambulatory electrocardiogram confirmed sinoatrial node dysfunction. Sinus node dysfunction in this paper refers to less than 40 beats / min during sinus bradycardia, more than 2.25 seconds in atrial arrest, or paroxysmal atrial tachycardia. In addition to distal conduction abnormalities, other heart disease are to be removed. Nine patients were measured
