This a 49-year-old male patient who at the age of 24 underwent surgical closure of an ostium secundum atrial septal defect with a prosthetic patch. One year before the procedure, he began complaining of recurrent palpitations, documented at 12-lead ECG as atrial flutter with 240 ms cycle ...
Atrial Flutter ECG ReviewAtrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial rate in atrial fibrillation is 400 to 600 bpm. ...
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,准确地实现自动AF和...

Atrial Flutter: ECG Considerations Atrial flutter is one of the major tachycardias because it: occurs commonly; usually indicates the presence of underlying structural/electrical atrial disease; is associated with increased risk of thromboembolism, and has specific therapeutic implications, as described bel...

Temporary overdrive pacing can be an effective method for terminating reentry tachyarrhythmias, such as atrial flutter and paroxysmal supraventricular tachycardia. It involves depolarization of myocardium within a reentry circuit (the “excitable gap”), rendering the tissue refractory; this interruption ...
