Therefor intracardiac ECGs measured in the coronary sinus during sinus rhythm, atrial flutter and atrial fibrillation were processed and compared. After fragmentation into patterns, the data is analysed by Principal Component Analysis (PCA). Using this new representation of the original data a ...
The ablation catheter was entered the coronary sinus to guide electrical isolation, curing the tachycardia. The ECG returned to normal sinus rhythm. Through three years follow up, no AT recurrence.doi:10.4236/ojim.2011.13012Jie WangZhihong Zhao...
baseline features had similar performances to the ECG-alone model trained from scratch and outperformed the ECG-alone transfer learning model. This may be due to the fundamental difference between the ECG classification task and the coronary stenosis discrimination task. The model pre-trained for ECC ...
The inclusion criteria used for this study included (1) patients with typical myocardial ischemia-related symptoms (such as shortness of breath, chest tightness, chest pain, and palpitation) or positive results of examinations; (2) 18 years and above; (3) with sinus rhythm. The exclusion ...

An electrocardiogram (ECG) performed at hospital admission showed sinus rhythm; and 0.1 mm ST-segment depression and T-wave inversion in precordial leads from V-3 to V-6 and in the inferior leads Dll, Dlll and aVF (Fig. 1). Blood samples were obtained and serum troponin I levels were ...
ECG: The arrows revealed normal sinus rhythm with no significant ST changes in all leads Full size image Fig. 3 Coronary angiography: The arrows revealed nonobstructive coronary arteries in the left anterior descending artery (LAD;A), left circumflex artery (LCX;B), and right coronary artery (...
POAF is defined as patients who were in sinus rhythm before CABG but developed new-onset AF after CABG. AF was defined as an irregular heart rhythm without repetitive patterns and prominent P waves for at least 30 s. In this study, each patient underwent continuous electrocardiogram (ECG) ...
12-lead ECG and rhythm strips during tachycardia are diagnostic and may give an impression about the most likely diagnosis. Although ST is usually easy to diagnose on 12-lead ECG, the presence of first-degree AV block, which is not uncommon after cardiac surgery, may give ECG appearan...
95 Reporting of CAD may nonetheless be useful in appropriately selected patients (younger, sinus rhythm, low calcium burden) with the potential to reduce the need for a separate diagnostic angiogram. Given the challenge of rate control end-systolic CTA may be more appropriate in this cohort of ...
