An 8 year old girl with primary pulmonary hypertension and signs of heart failure was given 17.5 mg of verapamil injected into the pulmonary artery over 25 minutes to test for the reversibility of pulmonary arteriolar obstruction. Pulmonary artery pressure fell from 70/50 to 35/25 mm Hg. Treatment with 40 mg verapamil by mouth four times daily was started, and she was discharged. She gradually became asymptomatic and resumed the activities of a normal child of school age. On recatheterisation seven months later her pulmonary artery pressure was 30/10 mm Hg. She was still doing well 12 months after the start of treatment.
一名8岁原发性肺动脉高压且有心力衰竭体征的女孩，在25分钟内经肺动脉注射17.5毫克维拉帕米，以检测肺小动脉阻塞的可逆性。肺动脉压从70/50降至35/25毫米汞柱。开始每日4次口服40毫克维拉帕米治疗，随后出院。她逐渐无症状，恢复了正常学龄儿童的活动。7个月后再次导管检查时，她的肺动脉压为30/10毫米汞柱。治疗开始12个月后她仍情况良好。
