Ventricle arrythmias (VA) have different appearance and clinical significance. Their most serious forms lead quickly to circulatory collapse or even to the arrest of circulation and the condition of the patient requires immediate therapeutic intervention in the form of cardioversion or defibrillation and cardiopulmonary resuscitiation.
All other VA require a more detailed diagnostic evaluation of the given condition before the kind of treatment is chosen. This also implies that a possible basic structural heart affection is distinguished.
