A 67-year-old man without prior heart disease presented with atrial flutter, with a 12-lead electrocardiogram (ECG) suggestive of typical atrial flutter. The patient underwent electrophysiology study and was found to have atypical atrial flutter, with entrainment mapping indicating likely left-sided ...
On ECG, the hallmark pattern is “saw-toothed” flutter waves, which are best viewed in leads II, III, and V1. The atrial rate is on average approximately 300 atrial bpm.3 Since the AV node cannot respond this quickly, there is an AV block that can present as a 2: 1, 3: 1, or...
五、结论 该机制使用11层CNN-IENN模型可以自动区分ECG信号。在两个公共数据库上通过10倍交叉验证对提出的模型进行了验证,同时获得了比几种最新算法更好的分类结果。研究的主要发现是,CNN和IENN的集成不仅使模型能够从原始ECG数据中自学本质特征,而且有助于增强ECG信号分析的模型性能。此外,分类模型可以高效,准确地实...

The 12-lead ECG suggested atrial flutter with a cycle length of 180 ms (330 cycles/min or 5.5 Hz) pattern in all the leads. With an intrinsic ventricular rate of 86 bpm, the initial machine-based assessment was atrial flutter with 4:1 AV conduction. Multiple ECGs were recorded and a ...

Atrial flutter with 1:1 conduction and RBBB aberrancy. Background Atrial flutter with 1:1 conduction often presents with broad complex tachycardia (BCT), commonly misdiagnosed as ventricular tachycardia (VT). The utility of standard ECG algorithms for classification of BCT has not been evalu... ...
