Introduction: The primary objective of this study was to test whether
seven-day Holter recording improves the sensitivity of detecting dilated cardiomyopathy
(DCM) predictive criteria (DCMp) compared with 24-h Holter recording in
asymptomatic Doberman Pinscher (DP) dogs.
Animals: Twenty-eight asymptomatic DP dogs with normal echocardiographic examinations.
Methods: Dogs with normal echocardiographic examinations underwent seven-day
Holter monitoring. The presence of 50 ventricular premature complexes and
or one couplet/one triplet/one episode of ventricular tachycardia per 24-h period
was considered positive for DCMp.
Results: Five dogs were positive on the first day, and an additional six dogs tested
positive from day two to seven of the Holter recording. The number of dogs positive
for DCMp detected by four days was significantly different (p ¼ 0.031) compared
with the first-day Holter recording.
