心电图（ECG）图表是需求最高的医学视觉资料之一，因为学习者需要同时满足三个要素：波形的准确性、标注的清晰度以及并排对比。通用的图像提示词通常在这三方面都会失败。
本指南将为你提供一套实用的 ECG 提示词系统，以及 30 个可以直接在 SciDraw 中使用的模板。
使用场景：医学教育幻灯片、考试复习讲义、床旁教学以及可用于发表的论文概念图。
为什么 ECG 提示词通常会失败
大多数提示词过于简短，例如：“画一个三度房室传导阻滞的心电图”。这通常会生成艺术化的线条，缺失标注，或者在临床上间期不一致。
一个强大的 ECG 提示词应包含：
- 临床情景（什么心律或病理改变）
- 波形规则（PR、QRS、ST、T 波的具体表现）
- 版面结构（单条带 vs 并排对比）
- 标注要求（导联名称、箭头、间期标签）
- 教学背景（学生水平和预期的学习目标）
准确 ECG 图表的提示词公式
使用此结构：
Create a medical teaching ECG diagram of [condition].
Layout: [single strip / 2-panel / 4-panel comparison], white background.
Show leads: [lead II / V1-V6 / 12-lead summary].
Waveform rules: [PR/QRS/ST/T specifics].
Add labels: [key findings, arrows, interval values].
Style: clean textbook-style vector, high contrast, publication-ready.

branch decisions and common pitfalls.ECG exam review summary page with mini-strips and key diagnostic clues,
optimized for one-page print handout.
你可以通过仅替换疾病名称和波形规则来调整每个模板。
导出前的质量检查清单
- 波形在临床上是否合理？
- 导联名称和标注在幻灯片比例下是否清晰可读？
- 对比布局是否清晰地回答了一个教学问题？
- 间期数值和诊断线索是否进行了明确的标注？
- 配色方案是否足够简洁，以满足投影和打印的需求？
最终建议
如果你的输出结果看起来“美观但模糊”，请添加更严格的波形约束和明确的标注要求。在 ECG 视觉资料中，精准度胜过装饰性。
准备好生成你自己的 ECG 教学图表了吗？
