Small Animals: Not as common as atrial abnormalities
Large Animals: Uncommon
1. Ventricular Tachycardia
2. Ventricular Premature Complexes
3. Ventricular Fibrillation
4. Ventricular Asystole
- The complete absence of electrical cardiac activity
====Causes====Cardiac or systemic pathology, Electrolyte disturbances, Electric Shock, Untreated ventricular tachycardia, Hypoxia etc.
ECG Appearance: Flat base line
Treatment
Small Animals
- Cardiopulmonary resuscitation
- Epinephrine
5. Escape Rhythms
- These rhythms occur in an effort to maintain heart function when the SA or AV nodes are not functioning properly. Escape rhythms occur in pacemaker tissue found in the atria, around the AV node, or in the ventricles. These ectopic rhythms occur at a regular, but slower depolarization rate compared to the dominant SA and AV nodal pacemakers.
ECG Appearance: Depending on where the escape rhythms originate, they can appear either as ectopic beats with a normal or totally abnormal shape.
====Treatment==== Do not use antiarrhythmic drugs in the presence of escape rhythms or else you risk death.
