心动过缓-心动过速综合征(BTS),系病态窦房结综合征的一种特殊类型,为老年人较易罹患的一种心律失常。患者常因突然发作室上性快速性心律失常或心率骤然减慢和心脏停搏而引起头晕、心悸、胸闷,乃至晕厥发作。对这类患者的治疗,使用抗心律失常药物极为困难。近来,我们对经多种抗心律失常药物治疗无效的2例 BTS 老年患者,在给予较小剂量乙胺碘呋酮治疗后,成功地终止了频繁发作的心动过速和晕厥,且未发生严重的心脏副反应。兹特介绍于下。
Bradycardia - tachycardia syndrome (BTS), a special type of sick sinus syndrome, is more susceptible to arrhythmias in the elderly. Patients often due to sudden onset of supraventricular tachyarrhythmia or sudden cardiac arrest and cardiac arrest caused dizziness, palpitations, chest tightness, and even syncope. The treatment of such patients, the use of anti-arrhythmic drugs is extremely difficult. We recently successfully discontinued frequent episodes of tachycardia and syncope without serious disease in 2 elderly patients with BTS who were refractory to multiple antiarrhythmic drug treatments after treatment with a lower dose of amiodarone Heart side reaction. Zit introduced below.
