See the below EKG of atrial fibrillation with aberrancy (likely a left bundle). Notice how this is a wide complex irregular tachycardia, and with each beat the morphology of the QRS is almost exactly the same.

2024年7月24日 · Atrial fibrillation (AFib) with ECG aberrancy means the ECG shows AFib with an issue in the heart’s conduction system. Treatment for AFib with aberrancy may depend on the type and severity of ...

2021年2月15日 · Atrial fibrillation in the presence of either bundle branch block or pre-excitation (accessory pathway) will result in an irregular wide complex tachycardia that may be mistaken for polymorphic VT. It is important to carefully check the ECG for the typical highly irregular rhythm of …

2024年10月8日 · Atrial fibrillation (AF) is the most common sustained arrhythmia. It is characterised by disorganised atrial electrical activity and contraction. The incidence and prevalence of AF is increasing. Lifetime risk over the age of 40 years is ~25%.

In clinical practice aberration is commonly seen in patients with atrial fibrillation because these patients have rapid and irregular rhythms with frequently changing RR intervals. Refer to Figure 2. Aberrancy can occur in three different situations, all related to changes in cardiac cycle length. These situations are as follows:

2023年1月31日 · Atrial fibrillation (AF) occurs in 20% of patients with Wolff-Parkinson-White (WPW) pattern, and atrial flutter in 7%; The presence of an accessory pathway (AP) allows for rapid conduction directly to the ventricles, bypassing the AV node

Atrial fib often displays aberrant conduction, especially when a beat follows closely after a long R-R cycle followed by a short R-R cycle. The refractory period is set by the preceding cycle. So a lont R-R causes a longer refractory period.

2023年1月31日 · Atrial fibrillation with slow ventricular response. Severe AV nodal disease; Hypothermia; Medications: Digoxin toxicity, Calcium-channel blocker / beta-blocker toxicity

2025年2月2日 · Ashman phenomenon is an aberrant ventricular conduction that follows a short R-R interval preceded by a long R-R interval. It is a physiological aberrancy and is typically seen in atrial fibrillation, but it can also be seen in atrial tachycardia or in …

tachycardia. In each patient, the clinical rhythm disturbance was reproduced and identified as atrial fibrillation or flutter with left bundle branch block aberrancy. All five patients demonstrated enhanced or accelerated atrioventricular conduction through the normal atrioventricular nodal-His Purkinje pathway.
