Six patients with atrial fibrillation who were taking digitalis were exercised before and after 30 mg. of propranolol twice daily. Though there was a lower pulse rate at rest and on exercise in all patients, three suffered deterioration of exercise tolerance. It is concluded that propranolol does not improve the exercise tolerance of patients with atrial fibrillation whose resting ventricular rate is controlled with digitalis.
六名正在服用洋地黄的房颤患者在每日两次服用30毫克普萘洛尔前后进行了运动测试。尽管所有患者静息和运动时的心率均降低,但三名患者的运动耐量却恶化了。结论是,对于静息心室率已用洋地黄控制的房颤患者,普萘洛尔并不能改善其运动耐量。
