Electrocardiography (ECG) and 24 hours Holter monitoring (24 h-Holter) provided valuable information for premature ventricular and supraventricular contractions (PVC and PSVC). Currently, artificial intelligence (AI) based 2 hours single-lead Holter (2 h-Holter) monitoring may provide an improved strategy for PSVC/PVC diagnosis.
AI combined with single-lead Holter monitoring improves PSVC/PVC detection.
In total, 170 patients were enrolled between August 2022 and 2023. All patients wore both devices simultaneously; then, we compared diagnostic efficiency, including the sensitivity/specificity/positive predictive-value (PPV) and negative predictive-value (NPV) in detecting PSVC/PVC by 24 h-Holter and 2 h-Holter.
The PPV and NPV in patients underwent 2 h-Holter were 76.00%/87.50% and 96.35%/98.55, respectively, and the sensitivity and specificity were 79.17%/91.30%, and 95.65%/97.84% in PSVC/PVC detection compared with 24 h-Holter. The areas under the ROC curves (AUCs) for PSVC and PVC were 0.885 and 0.741, respectively (p < .0001).
The potential advantages of the 2 h-Holter were shortened wearing period, improved convenience, and excellent consistency of diagnosis.
心电图（ECG）和 24 小时动态心电图监测（24 h-Holter）为室性和室上性早搏（PVC 和 PSVC）提供了有价值的信息。目前，基于人工智能（AI）的 2 小时单导联动态心电图监测（2 h-Holter）可能为 PSVC/PVC 诊断提供一种改进策略。
AI 与单导联动态心电图监测相结合可提高 PSVC/PVC 的检出率。
2022 年 8 月至 2023 年期间共纳入 170 例患者。所有患者同时佩戴两种设备；然后，我们比较了 24 h-Holter 和 2 h-Holter 检测 PSVC/PVC 的诊断效率，包括敏感性/特异性/阳性预测值（PPV）和阴性预测值（NPV）。
2 h-Holter 组的 PPV 和 NPV 分别为 76.00%/87.50%和 96.35%/98.55%，其在 PSVC/PVC 检测中的敏感性和特异性分别为 79.17%/91.30%和 95.65%/97.84%，均优于 24 h-Holter。PSVC 和 PVC 的 ROC 曲线下面积（AUC）分别为 0.885 和 0.741（p<0.0001）。
2 h-Holter 的潜在优势在于佩戴时间缩短、便利性提高和诊断一致性良好。
