BACKGROUND
This study estimates atrial repolarization activities (Ta waves), which are typically hidden most of the time from body surface electrocardiography when diagnosing cardiovascular diseases. The morphology of Ta waves has been proven to be an important marker for the early sign of inferior injury, such as acute atrial infarction, or arrhythmia, such as atrial fibrillation. However, Ta waves are usually unseen except during conduction system malfunction, such as long QT interval or atrioventricular block. Therefore, justifying heart diseases based on atrial repolarization becomes impossible in sinus rhythm.
METHODS
We obtain TMPs in the atrial part of the myocardium which reflects the correct excitation sequence starting from the atrium to the end of the apex.
RESULTS
The resulting TMP shows the hidden atrial part of ECG waves.
CONCLUSIONS
This extraction makes many diseases, such as acute atrial infarction or arrhythmia, become easily diagnosed.
背景
本研究估计心房复极活动（Ta 波），当诊断心血管疾病时，Ta 波的形态通常隐藏在体表心电图的大部分时间内。Ta 波的形态已被证明是下壁损伤的早期标志，如急性心房梗死，或心律失常，如心房颤动。然而，Ta 波通常除了在传导系统功能障碍时才可见，如长 QT 间期或房室传导阻滞。因此，在窦性节律下，基于心房复极来证明心脏病是不可能的。
方法
我们获得了心肌心房部分的 TMP，它反映了从心房到心尖结束的正确兴奋顺序。
结果
得到的 TMP 显示了 ECG 波的隐藏心房部分。
结论
这种提取使得许多疾病，如急性心房梗死或心律失常，变得容易诊断。
