Left Axis Deviation

- 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]
- 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]
- If the aberrancy is conducted in a LBBB pattern, left axis deviation will be present.[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]
- Aberration is seen as bundle branch block pattern (wide QRS complex).[metealpaslan.com]
- New algorithm using only lead aVR for differential diagnosis of wide QRS complex tachycardia.[e-arrhythmia.org]
- A new approach to the differential diagnosis of a regular tachycardia with a wide QRS complex.[usmlenotebook.tumblr.com]
- A wide QRS complex with a right BBB was noted in the baseline ECG (see Figure 1 ).[patientcareonline.com]
