- The cardinal features of fascicular VT are a right bundle branch block pattern with left axis deviation and a QRS duration of 0.11 0.14 seconds.[rcemlearning.co.uk]
- There is also extreme left axis deviation with small r-waves in inferior leads followed by a large S-wave, and a small q-wave in aVL with a large R-wave; this is a left anterior fascicular block (LAFB) morphology.[epmonthly.com]
- On the other hand, SVT with aberrant conduction will exhibit a mix of upright and inverted complexes throughout the precordial leads (Figure 3).6 Electrical axis SVTs with aberrancy will produce either a right or left axis deviation.[emsworld.com]

QRS Wave
Wide QRS Complex
- If the impulse is too premature , it may find one of the bundle branches still refractory from the previous impulse and will be conducted with a wide QRS complex . these premature atrial impulses that are followed by wide QRS complexes are aberrantly[afghanheart.wordpress.com]
- This results in bundle branch block and hence " wide QRS complex ". Clinical significance Identification of the wide QRS complex as aberration helps to exclude the diagnosis of VPS . ECG 1a.[metealpaslan.com]
- Several criteria have been described for differentiation between VT and SVT in the presence of a wide QRS complex. We report a case of wide QRS complex tachycardia with left BBB (LBBB) morphology and a retrograde P wave on the surface ECG.[e-arrhythmia.org]

Atrial Bigeminy
- Her ECG next day shows atrial bigeminy. Every P wave originating from the sinus node is followed by a premature P wave originating from an ectopic focus in the atria. The premature P wave is negative in the above ECG, suggesting a low atrial focus.[metealpaslan.com]
