普罗帕酮(心律平,Propafenone)是一种较新的、抗快速型心律失常的有效药物。临床电生理学研究表明,它的主要作用是延长心脏的有效不应期,减慢传导。急性试验或长期口服对窦房结无明显影响。我们最近遇到1例口服普罗帕酮引起的间歇性心脏停搏、窦房阻滞、及房室交界区逸搏心律伴有反文氏型Ⅱ度传导阻滞,较少见。特报告如下。患者,女性,56岁,1986年9月16日入院。反 Propafenone is a newer and more potent anti-tachyarrhythmia. Clinical electrophysiological studies have shown that its main role is to extend the effective refractory period of the heart, slowing the conduction. Acute or long-term oral administration of sinoatrial node no significant effect. We recently encountered one case of oral propafenone caused intermittent cardiac arrest, sinoatrial block, and atrioventricular junctional arrhythmias with anti-type Ⅱ degree of conduction block, rare. Special report is as follows. Patient, female, 56 years old, admitted to hospital on September 16, 1986. anti-
