Automated differentiation of wide QRS complex tachycardia using QRS complex polarity [PDF]

Communications Medicine
Background Wide QRS complex tachycardia (WCT) differentiation into ventricular tachycardia (VT) and supraventricular wide complex tachycardia (SWCT) remains challenging despite numerous 12-lead electrocardiogram (ECG) criteria and algorithms.

Identity Recognition Based on the QRS Complex Dynamics of Electrocardiogram

IEEE Access, 2020
Biometric identification based on electrocardiogram signals has attracted increasing attention. As the most dominant feature of the electrocardiogram signal, the QRS complex(i.e., the combination of ECG Q, R, and S waves) has been used for identification

Machine Learning Approach to Predict Ventricular Fibrillation Based on QRS Complex Shape

Frontiers in Physiology, 2019
Early prediction of the occurrence of ventricular tachyarrhythmia (VTA) has a potential to save patients’ lives. VTA includes ventricular tachycardia (VT) and ventricular fibrillation (VF).

Relationship Between Fragmented QRS Complex and Left Ventricular Fibrosis and Function in Patients With Danon Disease

Frontiers in Cardiovascular Medicine, 2022
BackgroundFragmented QRS (f-QRS) complex on the surface ECG is a cardiac conduction abnormality that indicates myocardial scarring. The relationship between the f-QRS complex and cardiac status in patients with Danon disease (DD) remains unclear and will

Narrow QRS complexes intervening wide QRS complexes [PDF]

Netherlands Heart Journal, 2012
An 80-year-old male was admitted to our hospital with complaints of palpitations. He was diagnosed with atrial fibrillation that stopped spontaneously one hour after admission (not shown). Before he was discharged the following ECG was recorded. How would you judge this ECG (Fig. 1) and, in particular, how would you explain the occurrence of narrow QRS
