The Ventricles

The ventricles are the chambers in the heart which receive blood from the atria and from which blood is forced into the arteries.

The term ventricular arrhythmia refers to any cardiac rhythm in which both the pacemaker site and conduction path are confined to the ventricles.

Two common examples of ventricular arrhythmia include:

Conduction irregularities that bypass the atrioventricular node will cause the ventricles to be stimulated early and not through the standard pathways. This is referred to as ventricular preexcitation.

Another problem associated with the ventricles is myocardial ischaemia. This indicates a reduced supply of oxygen to the muscle, often caused by narrowing of the arteries.
