【摘要】：心電圖是非侵入性診斷心律失常最常用的工具。然而,常規(guī)體表心電圖的空間分辨率很低,缺乏敏感性和特異性,且無法獲得心臟局部的電活動信息。而侵入性導管標測也存在很多局限性:無法同步標測全心房或全心室,對于血流動力學不穩(wěn)定的心律失常無法得到充足的時間進行標測等。一種新的無創(chuàng)心電成像技術(electrocardiographic imaging,ECGI)可能對心律失常的診斷和治療帶來便利。本文綜述了ECGI的臨床研究案例,包括心室再同步化治療、室性心律失常、房性心律失常和心房顫動等,為新技術的推廣打下基礎。
[Abstract]:Electrocardiogram (ECG) is the most commonly used tool for non-invasive diagnosis of arrhythmia. However, the spatial resolution of conventional surface electrocardiogram is very low, lack of sensitivity and specificity, and the local electrical activity information of the heart can not be obtained. However, invasive catheter mapping also has many limitations: it is impossible to simultaneously map the whole atrium or ventricle, and can not get enough time to map arrhythmias with unstable hemodynamics. A new non-invasive electrocardiography (electrocardiographic imaging,ECGI) may facilitate the diagnosis and treatment of arrhythmia. This paper reviews the clinical studies of ECGI, including ventricular resynchronization, ventricular arrhythmias, atrial arrhythmias and atrial fibrillation.
