Learn about aberrant ventricular conduction (aberration, aberrancy), emphasis on causes, ECG characteristics, clinical implications, management.

Aberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused with a ventricular ectopic beat.

2024年8月27日 · By understanding the concepts of aberrant conduction and the characteristics of SVT and VT, healthcare professionals can improve patient care and outcomes. What Is SVT With Aberrancy? The term “SVT with aberrancy” tends to throw many providers off, so let’s start by defining SVT using the 2015 ACC/AHA/HRS Guidelines as a reference.

The term aberration (or aberrant ventricular conduction) is used to describe transient bundle branch block and fascicular block that are unrelated to preexisting bundle branch block, preexcitation, or the effects of drug or electrolyte abnormalities.

2022年9月12日 · It is important to recognise aberrant ventricular conduction in the context of a broad complex tachycardia, as the differentiation between supraventricular tachyarrhythmias with aberrant ventricular conduction and ventricular tachyarrhythmias carry different therapeutic and prognostic implications.

2000年6月12日 · Aberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused with a ventricular ectopic beat.

2023年5月1日 · Aberrant ventricular conduction is a physiologic phenomenon resulting from relative refractoriness within components of the conduction system and can be observed at rapid ventricular rates and short coupling intervals.

2000年11月1日 · Aberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting system.

Cardiac aberrancy is a type of disruption in the shape of the electrocardiogram signal, representing abnormal activation of the ventricular heart muscle via the electrical conduction system of the heart.

2024年10月8日 · Aberrant conduction via an AP leads to early ventricular depolarisation (pre-excitation), which manifests as a short PR interval and slurred upstroke of the QRS complex; Conduction still occurs via the AV node, and is actually a brake on AP conduction, ceasing its propagation path in the ventricle
