小剂量多巴胺可加速心房纤颤患者的房室传导,从而出现过快心室率并伴血流动力学改变等不良反应。现将所见4例报告如下。 例1 男,68岁。心悸气促伴反复浮肿4月,于1988年12月4日入院。体检:T 36.5℃,BP16.0/12.0kPa(120/90mmHg)。双肺底细湿啰音,心界向双侧明显扩大,HR88次/分,节律不齐,心尖区可闻及Ⅱ级收缩期杂音。肝肋下2cm,触痛,双下肢水肿。经ECG、X线胸片与2 DPE等检查, Small doses of dopamine can accelerate atrioventricular conduction in patients with atrial fibrillation, resulting in excessive ventricular rate and hemodynamic changes associated with adverse reactions. Now see 4 cases reported as follows. Example 1 male, 68 years old. Heart palpitations with repeated edema April, on December 4, 1988 admission. Physical examination: T 36.5 ° C, BP ​​16.0 / 12.0 kPa (120/90 mmHg). Dual lungs at the end of wet rales, heart significantly expanded to both sides, HR88 beats / min, irregular rhythm, apex area can be heard and Ⅱ systolic murmur. Liver ribs 2cm, tenderness, lower extremity edema. The ECG, X-ray and 2 DPE and other tests,
