In the Lifetime Cardiac Study (USA) 2.6 % of
asymptomatic hounds had PVCs on the entry EKG.
In this population of 65
asymptomatic hounds with PVCs on a screening EKG, 17 or 26.1 % did NOT have PVCs on subsequent EKGs.
In Germany 2.6 % of hounds were reported to have PVCs on screening EKGs done at a veterinary hospital in
asymptomatic hounds.
This plus the surprising number of serious arrhythmias found on holter monitors in this population suggest PVCs are NOT ALWAYS a benign arrhythmia in
an asymptomatic hound.
PVCs in
an asymptomatic hound with a benign holter monitor exam are felt to be a benign arrhythmia in the Irish wolfhound.
