A circumferential 10-electrode catheter was used to pulmonary vein mapping during sinus rhythm or CSd pacing to determine the origin of atrial premature contractions. 10极的环状标测电极在窦性心律或者冠状窦远端(CSd)起搏的情况下标测肺静脉,确定房性早搏发生的起源;
Conclusion The normobaric oxygen therapy enhanced the oxygen pressure in fetal blood, increases the supply and utilization of oxygen, and reduces the atrial premature contractions effectively and safely. 结论常压氧疗法可明显提高胎儿血氧分压,增加胎儿氧的供应和利用,有效治疗胎儿房性心律失常。
