Case Report: Pseudo-wide QRS complex tachycardia in an infant with complex congenital heart disease [PDF]
Frontiers in PediatricsThe initial electrocardiogram (ECG) of a 5-month-old infant with complex congenital heart disease (pulmonary valvular stenosis, ventricular septal defects, and patent ductus arteriosus) revealed a regular wide QRS tachycardia at 169 bpm, initially ...

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

Spatial distribution of physiologic 12-lead QRS complex [PDF]
Scientific Reports, 2021 The normal physiologic range of QRS complex duration spans between 80 and 125 ms with known differences between females and males which cannot be explained by the anatomical variations of heart sizes. To investigate the reasons for the sex differences as

Wide QRS Complex After Catheter Ablation [PDF]
Circulation, 2018 A 20-year-old man with recurrent supraventricular tachycardia (Figure 1) was referred for catheter ablation. The baseline ECG (Figure 2) showed sinus rhythm with a PR interval of 0.20 seconds and QRS duration of 0.085 seconds. Application of irrigated radiofrequency current to a site 8 mm below the apex of Koch’s triangle was terminated after 18 ...
