Aberrant conduction occurs when the length of the cardiac cycle is changed without a compensatory change in the length of the refractory period. This is explained by the changes in the refractoriness in …

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 …

Aberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting …

Aberrant conduction describes a temporary deviation where an electrical impulse originating above the ventricles travels down an unusual path. It typically appears as a wider and differently shaped …

Nov 15, 2024 · 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.

Explore ECG insights on supraventricular impulses, ventricular conduction, QRS complex, action potentials, refractory periods, and aberrant conduction.

Jun 11, 2025 · When confronted with a wide QRS complex that appears unexpectedly on an ECG, one of the key clinical challenges is to determine whether it's due to a premature ventricular contraction …

May 1, 2023 · This review will define the ECG footprints of aberrant ventricular conduction to allow accurate ECG interpretation.

Note: To distinguish aberrancy from a fixed ventricular conduction defect, one or more normally conducted QRS complexes or a prior ECG showing a normal QRS complex should be observed.

Aug 29, 2025 · Also known as bypass tracts, APs are abnormal conduction pathways formed during cardiac development and can exist in a variety of anatomical locations and in some patients there …
