Figure 4: Simultaneous recording of both aortic and right pulmonary artery pressures (a) are almost similar with a 6 mmHg difference between the two vessels. After balloon occlusion of the right-sided arterial duct (b), an increase of aortic pressure and fall of right pulmonary artery pressure was accompanied by a relative bradycardia due to Branham effect
