VPC Arrhythmias in Irish Wolfhounds

Ventricular premature contractions (VPCs) are heart rhythm disturbances that interrupt the normal heart rhythm.

In Boxers and Dobermans, VPCs can signal a condition that frequently leads to sudden death. In wolfhounds, VPCs appeared to be more benign. However, in preliminary data, serious VPCs that could lead to sudden death have been found in some wolfhounds.

The holter monitor records the heart’s activity for a period of 24 hours. It is an excellent tool for evaluating VPCs. The purpose of this study is to evaluate the incidence of dangerous arrhythmia in Irish Wolfhounds found to have VPCs in screening ECGs that are otherwise normal.

You will be reimbursed for the following tests required for the study:

1. Yearly echocardiogram performed by a board certified cardiologist. (An echo obtained at one of the IWF Echo Clinics is fine.)
2. Annual holter monitor testing plus one extra holter if medication is prescribed.
3. Blood tests: CBC, Chemistry panel, Thyroid (T4) and Tick Panel (one time only on entry)

The digital holter monitor can be arranged through a board-certified cardiologist of your choice. During the 24 hour period you will be asked to keep a diary of your dog’s activities.

The Irish Wolfhound Foundation will contact your veterinarian and/or cardiologist to arrange for submission of results.

Participation Requirements

Any Irish Wolfhound known to be free of heart disease other than VPCs is eligible for entry into this study.
