What Is A Vpc In Dogs

Ventricular premature complex vpc aka ventricular premature contraction is a type of irregular heartbeat.

What is a vpc in dogs. The ventricular escape complex happens after a pause and occurs as an idioventricular rhythm which discharges at 20 40 times minute in a dog. Atrium and two bottom chambers are the ventricles. Secondary myocardial disease can result from viral bacterial mycotic and protozoal infections hyperthyroidism hypothyroidism anemia malnutrition electrolyte imbalances.

Low grade arrhythmias grade i ii i e. There are different treatment protocols recommended at the moment. Vpc s and ventricular tachycardia v t that may develop are indications of myocardial irritation or inflammation.

Ventricular premature complexes vpc are diagnosed in a number of boxers with or without clinical signs of syncopal episodes. A small proportion of dogs will develop heart muscle failure that could lead to signs. This also includes ventricular bigeminy and trigeminy every other beat is a vpc or every other two beats are a vpc respectively.

When the impulse arises prematurely from the ventricle it is called ventricular premature complex vpc. The specific arrhythmia with this disease is called ventricular premature complexes vpc these are early abnormal heart beats originating from the heart muscle instead of the specialized conduction tissue in the heart where normal heart beats originate. An electrical impulse is initiated within the ventricles instead of the sa node causing the ventricles to contract too early thus the premature in ventricular premature complex.

This electrical conduction system generates electrical impulses waves which propagate throughout the musculature of the heart stimulating the heart s muscles to contract and push blood through the interior arteries and out into the body. This is not a ventricular arrhythmia and must not be treated as so. Ventricular premature complexes in dogs the heart has an electrical conduction system that is responsible for controlling the heart rate.

Under normal circumstances the heart works with exceptional synchronization between the various atrial and ventricular structures resulting in a consistent rhythmic pattern. Which of the four most commonly used is the best.
