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 fo

先将MITDB数据库中的ECG记录从360 Hz下采样到250 Hz。另外,由于原始的ECG信号经常被不同类型的噪声所污染,例如电力线干扰,基线漂移和肌肉噪声 [31],这些伪影使用Daubechies小波6进行去噪处理。随后,将经过滤波的ECG信号以4 s的长度进行分段,并根据注释进行分类,每个ECG分段包含1000个采样点。然后在将心电图片段进行...
Atrial Flutter The atrial flutter is a supraventricular arrhythmia caused by an intra-atrial macro-reentrant circuit. The main clinical manifestation depends on ventricular response, and it may includes palpitations, shortness of breath and dizziness, sometimes thromboembolism with transient ischemic attack...
“classic” atrial flutter, typical ECG findings include negative flutter waves in the inferior leads (II, III, and aVF) instead ofP waves, with atrial rates of 250 to 450 beats/min. This type of atrial flutter usually involves the isthmus between theinferior vena cavaand thetricuspid valveas...
Electrocardiogram (EKG or ECG).In this quick, painless, noninvasive test, electrodes are attached to your chest, arms, and legs in order to measure and record your heart’s electrical activity. If you are in an episode of atrial flutter, your EKG reading will show that. ...
Diagnosis of atrial flutter: The diagnosis of atrial flutter is based on the symptoms, on the physical examination and on the ECG interpretation. Symptoms. Severity of symptoms depends on the ventricular rate and heart condition. May be present: palpitations, dizziness, anxiety, faintness, shortnes...
Similar to atrial fibrillation except for ECG findings (see “Diagnosis of atrial fibrillation”) Characteristic ECG findings of atrial flutter Rate: typically 75–150/minute (depending on conduction) [61] Atrial rate ≥ ventricular rate Regular, narrow QRS complexes The rhythm may be: Reg...
Atrial fibrillation (AF) is an arrhythmia that can cause blood clot and may lead to stroke and heart failure. To detect AF, deep learning-based detection algorithms have recently been developed. However, deep learning models were often trained with limit
