Cardiac aberrancy
# Cardiac aberrancy

Cardiac aberrancy is a type of aberration in the shape of the EKG signal, representing activation of the heart muscle via the electrical conduction system of the heart. Aberration occurs when the electrical activation of the heart, which is caused by a series of action potentials is conducting improperly, which can be due to:

* left anterior fascicular block
* left posterior fascicular block
* bundle branch block
* Wolff–Parkinson–White syndrome
