持续性单形性室性心动过速 vs 房室结折返性心动过速（慢-快型）: 临床与心电图鉴别
基于MioAtlas 3D心脏模拟器模型的持续性单形性室性心动过速与房室结折返性心动过速（慢-快型）横向对比。
按解剖生理分层与诊断参数列出的表现
| 层面 / 表现 | 持续性单形性室性心动过速 | 房室结折返性心动过速（慢-快型） |
|---|---|---|
| 临床概要 |
连续 ≥ 3 次室性心搏，频率 > 100 bpm，伴一致的QRS波形态。通常由心肌瘢痕（心肌梗死后）周围的折返引起。特征包括房室分离（独立的P波、室性融合波、心室夺获）及极度电轴偏移。 |
正常心脏成年人中最常见的阵发性室上性心动过速。房室结内的功能性环路利用前向慢径路和逆向快径路折返。逆行P波埋入QRS波群内或紧随其后，在V1导联模拟假性r'波，在下壁导联模拟假性S波。 |
