When Should Ventricular Premature Complexes (VPCs) Be Treated?

Veterinary technicians are often tasked with close monitoring of patients post-operatively, and during anesthesia. It is important to monitor for Ventricular Premature Complexes so that you may notify the doctor (especially after and during procedures such as GDV and splenectomy where they are commonly seen).

You may also perform routine ECGs in patients as part of a regular checkup or in patients that have known heart disease. There are many dogs that may have intermittent VPCs that are not clinically significant, but if they are noted the patient should have regular monitoring and consult with a cardiologist. It is helpful to know the criteria of when we recommend treatment for them.

There are a few general guidelines about treatment of ventricular premature contractions such as the ones seen here on this ECG strip:

                                VPCs2

Treatment is recommended if any of the following are observed:

  • Heart rate over 180 beats per minute
  • Pulse deficits
  • Clinical symptoms of VPC’s (weakness, syncope, exercise intolerance, coughing, etc.
  • VPCs that are lasting over 20 seconds in duration

Treatment will depend on the underlying cause of the VPCs and if tachycardia and/or underlying heart disease is present.

Treatments may include a lidocaine bolus and CRI if it is a post-operative issue and is transient, or may include Beta-blockers (such as atenolol or sotalol) for dogs with chronic cardiomyopathy (such as in Boxers).
