摘要

辅助通路定位算法被广泛应用于室性预激患者的导管消融规划。这些算法通常依赖于δ波和QRS复合体的特征来预测AP的位置。然而，诸如解剖变异、年龄、多个ap的存在和患者生物型等因素可能导致不准确。我们报告了一例心室预兴奋但无合并症的患者，其心电图（ECG）显示的AP位置与标准算法预测的完全不同。这种差异导致导管消融策略的改变，通过逆行主动脉入路成功地进行了消融。

Algorithms for locating accessory pathways: How far should we trust?

Algorithms for locating accessory pathways (APs) are widely used in planning catheter ablation for patients with ventricular preexcitation. These algorithms typically rely on characteristics of the delta wave and QRS complex to predict AP location.

However, factors such as anatomical variations, age, the presence of multiple APs, and patient biotype can lead to inaccuracies.

We present the case of a patient with ventricular preexcitation but no comorbidities, whose electrocardiogram (ECG) suggested an AP location entirely different from that predicted by standard algorithms. This discrepancy led to a change in the catheter ablation strategy, which was successfully performed via a retrograde aortic approach.

期刊介绍： The Journal of Electrocardiology is devoted exclusively to clinical and experimental studies of the electrical activities of the heart. It seeks to contribute significantly to the accuracy of diagnosis and prognosis and the effective treatment, prevention, or delay of heart disease. Editorial contents include electrocardiography, vectorcardiography, arrhythmias, membrane action potential, cardiac pacing, monitoring defibrillation, instrumentation, drug effects, and computer applications.
