Although electrophysiological study (EPS) is one of the most useful diagnostic approaches to detect the cardiac origin of palpitations, there is no clear indication for EPS in patients with palpitation in the absence of documented supraventricular tachycardia (SVT). In this study, we aimed to create a new SVT score model to detect the requirement of EPS in patients with palpitation without documented tachycardia.
A total of 154 patients with palpitation were included in this study. To create the SVT score, we considered four main criteria with their subunits. They were severity, frequency, duration, and termination of the symptoms. EPS was performed on all the patients after their scoring assessment.
Median SVT score of induced tachycardia and non-induced patients was determined as 10 and 6 points, respectively; and it was found to be statistically significant; p<0.001. The cut-off value for inducibility was found to be 7.5 points through receiver operating characteristic curve analysis, (94.9% sensitivity, 92.1% specificity), and the area under the curve was determined to be 97.2 (94.8-99.5, p<0.001).
According to our new SVT score model, ≥8 points strongly correlates with the inducibility of SVT during EPS.
尽管电生理研究（EPS）是检测心悸的心脏起源的最有用的诊断方法之一，但在没有记录到室上性心动过速（SVT）的情况下，对于心悸患者，没有明确的 EPS 指征。在这项研究中，我们旨在创建一个新的 SVT 评分模型，以检测无记录心动过速的心悸患者是否需要进行 EPS。
本研究共纳入 154 例心悸患者。为了创建 SVT 评分，我们考虑了四个主要标准及其子单元。它们是症状的严重程度、频率、持续时间和终止。在评分评估后，对所有患者进行 EPS。
诱导性心动过速和非诱导性患者的 SVT 评分中位数分别为 10 分和 6 分，且具有统计学意义（p<0.001）。通过受试者工作特征曲线分析，发现可诱导性的截断值为 7.5 分（94.9%的敏感性，92.1%的特异性），曲线下面积为 97.2（94.8-99.5，p<0.001）。
根据我们的新 SVT 评分模型，≥8 分与 EPS 期间 SVT 的可诱导性强烈相关。
