To present the content, data quality, and research potential of the West Jutland Tele-Electrocardiogram Registry (WEJU-tECG).
Danish patients reporting symptoms indicating heart disease in the prehospital setting are subjected to a 12-lead tele-electrocardiogram (ECG) in the ambulance, which is digitally sent to a local tele-centre. WEJU-tECG is a newly established Danish registry containing information from the individual tele-ECGs received at the Regional Hospital West Jutland tele-centre.
WEJU-tECG holds extracted information from all tele-ECGs with a valid Civil Personal Register number between 2011 and 2020. WEJU-tECG contains information on patient characteristics, tele-ECG data (including a computerised tele-ECG interpretation), vital signs, and time information. A unique Civil Personal Register number allows individual-level linkage between WEJU-tECG and other Danish registries and enables complete follow-up. WEJU-tECG contains 43,696 tele-ECGs from 29,489 different patient contacts among 20,280 different patients. WEJU-tECG contains 5566 patients with ST-segment deviations. The median age is 67 years and 45% are women. Completeness is highest for time information (100% for all variables), tele-ECG data (99% for heart rate, the specific intervals and axes, and QRS duration, and 86% for J-point deviation), and patient characteristics (100% for all variables). Completeness is lowest for vital signs (13% for systolic, diastolic, and mean arterial blood pressure, and 12% for blood oxygen saturation). The computerised tele-ECG interpretation had a negative predictive value of 80% for ST-segment elevation myocardial infarction and 94% for non-ST-segment elevation myocardial infarction and a positive predictive value of 45% for ST-segment elevation myocardial infarction and 32% for non-ST-segment elevation myocardial infarction.
WEJU-tECG is a novel population-based tele-ECG registry with high research potential.
介绍 West Jutland 远程心电图登记处（WEJU-tECG）的内容、数据质量和研究潜力。
在院前环境中报告有心脏病症状的丹麦患者在救护车上接受 12 导联远程心电图（ECG）检查，心电图以数字方式发送到当地远程中心。WEJU-tECG 是一个新建立的丹麦登记处，包含在 West Jutland 地区医院远程中心接收的每个远程 ECG 信息。
WEJU-tECG 包含 2011 年至 2020 年间所有具有有效公民个人登记号的远程 ECG 的提取信息。WEJU-tECG 包含患者特征、远程 ECG 数据（包括计算机化的远程 ECG 解读）、生命体征和时间信息。独特的公民个人登记号允许在 WEJU-tECG 和其他丹麦登记处之间进行个体层面的链接，并实现完整的随访。WEJU-tECG 包含 43696 份远程 ECG，来自 20280 名不同患者的 29489 次不同患者接触。WEJU-tECG 包含 5566 名 ST 段偏移患者。中位年龄为 67 岁，女性占 45%。时间信息的完整性最高（所有变量均为 100%），远程 ECG 数据（心率、特定间隔和轴、QRS 持续时间的完整性为 99%，J 点偏移的完整性为 86%），以及患者特征（所有变量的完整性均为 100%）。生命体征的完整性最低（收缩压、舒张压和平均动脉血压的完整性为 13%，血氧饱和度的完整性为 12%）。计算机化的远程 ECG 解读对 ST 段抬高型心肌梗死的阴性预测值为 80%，对非 ST 段抬高型心肌梗死的阴性预测值为 94%，对 ST 段抬高型心肌梗死的阳性预测值为 45%，对非 ST 段抬高型心肌梗死的阳性预测值为 32%。
WEJU-tECG 是一个具有高研究潜力的新型基于人群的远程 ECG 登记处。
