老年人中,心房颤动(AF)很常见,其中多数伴有传导系统疾病;这类患者常呈慢室率AF,临床表现疲劳、头晕、昏厥或心力衰竭。起搏器对此有效。起搏指征 AF永久性起搏指征一般是心跳间歇或心动过缓伴有脑症状、药物(如β阻滞剂、某些钙拮抗剂、胺碘酮等)诱发的症状性心动过缓又不能停药、直流电房室结消融术(能有效控制抗药的AF,但可能损害房室结而导致完全性房室传导阻滞)之后,AF伴窦房结疾病及/或晚期房室传导阻滞作电复律之前,快一慢综合征在阵发性AF发作后呈症状性心动过缓(抗心律失常药不能足够控制阵发性
Atrial fibrillation (AF) is common in the elderly, most of which are associated with conduction system disease; these patients are often presented with slow ventricular AF, clinical manifestations of fatigue, dizziness, fainting or heart failure. Pacemakers effective. Indications for pacing AF Permanent pacing indications are generally intermittent or bradycardia with brain symptoms, symptomatic bradycardia induced by drugs (such as beta blockers, certain calcium antagonists, amiodarone, etc.) And can not stop the drug, DC atrioventricular ablation (AF can effectively control the drug resistance, but may damage the atrioventricular node and lead to complete atrioventricular block), AF with sinoatrial node disease and / or advanced atrioventricular Before conduction block for cardioversion, fast-slow syndrome was symptomatic bradycardia after paroxysmal AF episodes (anti-arrhythmic drugs can not adequately control paroxysmal
