摘要
目的 :总结 6 3例动脉导管未闭 (PDA)封堵术前后心电图 (ECG)改变。方法 :按 PDA直径分为≤ 0 .5 cm组 (4 0例 ) ,>5 0 cm组 (2 3例 )。每例均描记术前及术后 1周 12导联 ECG各 1次。观察不同直径 PDA对 ECG的变化 ,及介入封堵治疗对 ECG的影响。结果 :PDA直径≤ 0 .5 cm儿童与成人 ECG均以无心室肥厚为主 ;PDA直径 >0 .5cm,儿童均有心室肥厚 (9/ 9) ,14岁以上者正常与左室肥厚各占 1/ 2 ;封堵治疗术后 1周 度传导阻滞消失 ,1/ 3左室肥厚恢复正常 ,但 V5,V6ST- T改变加重。结论 :PDA的直径与 ECG表现有关 ;封堵治疗短期可使部分左室肥厚恢复正常 ,但 ST-
AIM:To study the changes of ECG in 63 cases with patent ductus arteries(PDA) before and after transcatheter closure. METHODS:Patients were divided according to the diameters of ductus into ≤0 5 cm (n=40) and >0.5 cm(n=23) groups respectively. The 12-lead ECG was performed before and one week after the operation. RESULTS:The patients with the diameter of ductus ≤0.5 cm did not develop ventricular hypertrophy (VH). While there were VH in all the children and half of the adults in the second group. The Ⅰ° atrial-ventricular blockade disappeared one week after transcatheter closure and one third of the patients with left ventricular hypertrophy recovered except those whose ST-T wave changes were deteriorated in V 5 and V 6 leads. CONCLUSION:The diameters of PDA were associated with ECG changes;The transcatheter closure could restore the VH in a short time,but worsened the ST-T wave changes.
