Ⅰ、心房负荷心电图 1.心房负荷心电图的概念作为P波异常的命名,现在使用着心房肥大、心房扩大、心房扩张、心房波异常、心房负荷等各种名称,还没有统一的见解。一般来说心房肌比心室肌显著的薄,血流动力负荷增加时,心房肌不太进行代偿性吧大,容易扩张。 Saunders等推荐叫作心房波异常。但是,即使叫作心房波异常也含有心房传导异常和异位性P波等,我们认为使用心房负荷更适当。
Ⅰ, atrial load ECG 1. atrial load ECG as the concept of P wave abnormalities, now using atrial hypertrophy, atrial enlargement, atrial expansion, atrial wave abnormalities, atrial load and other names, there is no unified opinion. In general, atrial fibrillation is significantly thinner than ventricular muscle, when the hemodynamic load increases, the atrial fibrillation is less compensatory and is likely to dilate. Recommended by Saunders et al is Atrial Wave Abnormal. However, even if it is called atrial wave abnormality, it contains abnormal atrial conduction and ectopic P wave, etc. We think that the use of atrial load is more appropriate.
