本研究估计心房复极活动(Ta波),这在诊断心血管疾病时通常是在体表心电图中隐藏的。Ta波的形态已被证明是判断下壁损伤如急性心房梗死或心律失常如房颤早期体征的重要标志。然而,Ta波通常不可见,除非传导系统出现故障,如长QT间期或房室传导阻滞。因此,在窦性心律中,根据心房复极来判断心脏病是不可能的。我们在心肌心房部分得到了TMPs,它反映了从心房到心尖末端的正确兴奋顺序。由此产生的TMP显示心电波的隐蔽心房部分。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。
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. 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. The resulting TMP shows the hidden atrial part of ECG waves. This extraction makes many diseases, such as acute atrial infarction or arrhythmia, become easily diagnosed.
