Ninety-two consecutive patients with atrial fibrillation (AF) who underwent dobutamine stress echocardiography were compared with a control group of patients in sinus rhythm matched for age, sex, and resting heart rate. Patients with AF had an increased chronotropic response to dobutamine, but there were no adverse effects and no evidence that the lower doses of dobutamine typically given to patients with AF were insufficient to induce ischemia.
将92例连续接受多巴酚丁胺负荷超声心动图检查的房颤（AF）患者与一组年龄、性别和静息心率相匹配的窦性心律对照组患者进行比较。房颤患者对多巴酚丁胺的变时反应增强，但未出现不良反应，也没有证据表明通常给予房颤患者的较低剂量多巴酚丁胺不足以诱发缺血。
