1 心房颤动 是房性异位起搏点的主动性快速性房内多灶微折返的极速心律失常。发生率在各种心律失常中占第三位,约占心律失常总数的12％～14％。 凡是导致心房病变和心力衰竭的器质性心脏病都能引起房颤。国内最常见的为冠心病、高血压性心脏病、甲状腺机能亢进性心脏病、心肌炎、缩窄性心包炎、急性肺心病等。另外,其他有预激综合征引起的房颤、心脏手术和外伤、纵隔肿瘤、胆囊炎、胆石症、内脏栓塞、烧伤、感染、低血钾、低血钠、低温、缺氧、洋地黄中毒、乌头碱类、尼古丁中毒、电复律术中或心房起搏中偶而发生房颤。酗酒和吸烟、情绪激动、剧烈运动、过度疲劳也可导致房颤。同时也有报道,药物如异搏定等,以及触电可引起房颤,月经期也能诱发房颤。
1 atrial fibrillation is atrial ectopic pacemaker rapidity of sexual activity within the multi-focal micro-reentry tachyarrhythmia. The incidence of various arrhythmias in the third place, accounting for about 12% to 14% of the total number of arrhythmias. Atrial fibrillation can occur in any organic heart disease that leads to atrial fibrillation and heart failure. The most common domestic coronary heart disease, hypertensive heart disease, hyperthyroidism heart disease, myocarditis, constrictive pericarditis, acute pulmonary heart disease. In addition, there are other pre-excitation syndrome caused by atrial fibrillation, cardiac surgery and trauma, mediastinal tumors, cholecystitis, cholelithiasis, visceral embolism, burns, infections, hypokalemia, hyponatremia, hypothermia, hypoxia, digitalis poisoning , Aconitine, nicotine poisoning, electrical cardioversion or atrial fibrillation occurs occasionally in atrial fibrillation. Alcoholism and smoking, emotional, strenuous exercise, fatigue can also lead to atrial fibrillation. Also reported, drugs such as verapamil, etc., as well as electric shock can cause atrial fibrillation, menstrual period can also induce atrial fibrillation.
