摘要
使用心外膜和胸壁心电图同时标测的方法观察19只犬结扎冠状动脉后ΣQ,ΣR、ΣST在二种标测图上的相互关系。结果表明,8只犬的ΣQ、13只犬的ΣR及19只犬的ΣST变化在二种标测图上表现良好相关。提示体表心电图对反映心外膜面的Q波和R波变化尚有一定局限性。
Nineteen dogs were studied to observe the relationship of ΣQ·ΣQ and ΣST on the chest wall and epicardium with simultaneous precordial and epicardial ECG mapping by occluding the left anterior descending coronary artery. The results revealed that changes of ΣQ of 8 dogs. ΣQ of 13 dogs and ΣST of 19 dogs on precordial and epicardial ECG mapping showed better correlation (correlation coefficients>0.6, p<0.05). These recults indicate that body surface ECG reflects the changes of Q and R waves on the epicardium with some limitation.
