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 ...

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...
Arrhythmias such as atrial fibrillation (AFIB), atrial flutter (AFL), and ventricular fibrillation (VFIB) are early indicators of stroke and sudden cardiac death, and the electrocardiogram (ECG) provides vital information for arrhythmia detection. In recent years, deep learning has been widely used...
Atrial fibrillation should be differentiated from atrial flutter and atrial tachycardia with varying A-V response. Tachycardia with wide QRS complexes (and an irregular ventricular response) are either due to aberrancy or to anomalous AV-conduction (WPW syndrome). Furthermore an irregular ventricular ...
(mostly paroxysmal), which is two-channel ECG signals each sampled at 250 samples per second with 12-bit resolution over a range ± 10 mV for 10 h. The rhythm annotation files were prepared manually. The rhythm annotations of types are atrial fibrillation (AF), atrial flutter (AFL), ...
The result will be classified as either Sinus rhythm, Atrial fibrillation, or Inconclusive. All ECG results will be synced to the phone app. You can view further information about the result of your ECG recording in the ECG app, and you can also share your ECG recordings with a clinician....
