Considering the adverse clinical consequences of pathologic tachycardia and the potential anxiety caused by physiological tachycardia in some heathy individuals, it is imperative to disseminate health information related to tachycardia for promotion in early diagnosis and appropriate management. YouTube has been increasingly used to access health care information. The aim of this study is to assess the quality and reliability of English YouTube videos focusing on tachycardia and further delve into strategies to enhance the quality of online health resources.
We conducted a search using the specific key words "tachycardia" in YouTube online library on December 2, 2023. The first 150 videos, ranked by "relevance", were initially recorded. After exclusions, a total of 113 videos were included. All videos were extracted for characteristics and categorized based on different topics, sources or contents. Two independent raters assessed the videos using Journal of American Medical Association (JAMA) benchmark criteria, Modified DISCERN (mDISCERN) tool, Global Quality Scale (GQS) and Tachycardia-Specific Scale (TSS), followed by statistical analyses. All continuous data in the study were presented as median (interquartile range).
The videos had a median JAMA score of 2.00 (1.00), mDISCERN of 3.00 (1.00), GQS of 2.00 (1.00), and TSS of 6.00 (4.50). There were significant differences in JAMA (P < 0.001), mDISCERN (P = 0.004), GQS (P = 0.001) and TSS (P < 0.001) scores among different sources. mDISCERN (P = 0.002), GQS (P < 0.001) and TSS (P = 0.030) scores significantly differed among various contents. No significant differences were observed in any of the scores among video topics. Spearman correlation analysis revealed that VPI exhibited significant correlations with quality and reliability. Multiple linear regression analysis suggested that longer video duration, sources of academics and healthcare professionals were independent predictors of higher reliability and quality, while content of ECG-specific information was an independent predictor of lower quality.
The reliability and educational quality of current tachycardia-related videos on YouTube are low. Longer video duration, sources of academics and healthcare professionals were closely associated with higher video reliability and quality. Improving the quality of internet medical information and optimizing online patient education necessitates collaborative efforts.
考虑到病理性心动过速的临床不良后果以及某些健康个体中生理性心动过速可能引起的焦虑，传播与心动过速相关的健康信息以促进早期诊断和适当管理至关重要。YouTube 越来越多地被用于获取医疗保健信息。本研究旨在评估聚焦心动过速的英文 YouTube 视频的质量和可靠性，并进一步探讨提高在线健康资源质量的策略。
我们于 2023 年 12 月 2 日在 YouTube 在线图书馆中使用特定关键词“心动过速”进行搜索。最初记录了按“相关性”排名的前 150 个视频。排除后，共纳入 113 个视频。根据不同主题、来源或内容对所有视频进行提取和分类。两名独立评估者使用美国医学会（JAMA）基准标准、改良 DISCERN（mDISCERN）工具、全球质量量表（GQS）和心动过速专用量表（TSS）评估视频，然后进行统计分析。研究中所有连续数据均以中位数（四分位距）表示。
视频的 JAMA 评分为 2.00（1.00），mDISCERN 评分为 3.00（1.00），GQS 评分为 2.00（1.00），TSS 评分为 6.00（4.50）。不同来源的 JAMA（P<0.001）、mDISCERN（P=0.004）、GQS（P=0.001）和 TSS（P<0.001）评分存在显著差异。不同内容的 mDISCERN（P=0.002）、GQS（P<0.001）和 TSS（P=0.030）评分存在显著差异。视频主题之间的任何评分均无显著差异。Spearman 相关分析显示 VPI 与质量和可靠性呈显著相关。多元线性回归分析表明，视频时长较长、来源为学术界和医疗保健专业人员是可靠性和质量较高的独立预测因素，而特定心电图信息内容是质量较低的独立预测因素。
目前 YouTube 上与心动过速相关的视频的可靠性和教育质量较低。视频时长较长、来源为学术界和医疗保健专业人员与视频可靠性和质量密切相关。提高互联网医疗信息质量和优化在线患者教育需要共同努力。
