摘要:
目的 观察和分析急性心肌梗死(AMI)患者Ⅲ度房室传导阻滞(AVB)与房室结动脉血供的关系。方法 将入选的AMI患者，按是否并发Ⅲ度AVB分为两组:病例组为AMI并发Ⅲ度AVB的患者（n=35例），对照组为AMI未并发Ⅲ度AVB的患者（n=215例），通过观察梗死相关动脉并分析房室结动脉血供来源情况，分析AMI患者不同房室结动脉血供来源发生Ⅲ度AVB的几率，并观察AMI并发Ⅲ度AVB的患者，房室结动脉血运改善后Ⅲ度AVB恢复时间。结果 房室结动脉血供来源于右冠状动脉的右上降支动脉和回旋支的kugel’s动脉之一或二者双重血供。病例组患者，其房室结动脉血供仅来源于右冠状动脉的右上降支或回旋支的kugel’s动脉，无前降支来源，并且右冠状动脉较回旋支多见（P<0.01）。当梗死相关动脉得到再灌注,恢复血运后,AVB均恢复到窦性心律。结论 急性心肌梗死Ⅲ度AVB发生患者与其房室结动脉血供中断有关，恢复房室结动脉血供后AVB恢复窦性心律。
Abstract:
AIM To observe and analyze the relationship between third-degree atrioventricular block of acute myocardial infarction (AMI) patients and blood supply of atrioventricular node artery. METHODS Acute myocardial infarction candidate patients, according to whether or not there was a concurrent degree of atrioventricular block (AVB) III, were divided into two groups. One group underwent acute myocardial infarction and third-degree atrioventricular block (n=35). The other group underwent acute myocardial infarction but without third-degree atrioventricular block (n=215). The origin of the atrioventricular node blood supply, the probability of the third-degree atrioventricular block of different sources of the artery of the atrioventricular node, and recovery time of third-degree atrioventricular block in restorative blood flow were compared. RESULTS The origin of the atrioventricular node artery blood is the descending artery of the right coronary artery and Kugel’s artery of the left circumflex. In the case group, the origin of the atrioventricular node artery blood is only from the descending artery of the right coronary artery or Kugel’s artery of the left circumflex, in which the right coronary artery was more than the left circumflex, but not the left anterior descending artery (P<0.01). When the infarction-related artery was reperfusioned and restored the blood supply, AVB returned to sinus rhythm. CONCLUSION AVB III is related to the interruption of the atrioventricular node artery. After recovery of the atrioventricular node artery blood, AVB III returns to sinus rhythm.
