To evaluate the use of 24-hour ambulatory electrocardiography (AECG) for the detection of ventricular premature complexes (VPC) in healthy dogs.
Case series.
50 healthy mature dogs.
A 24-hour AECG was performed on each dog and evaluated for the presence of VPC.
Fifty dogs weighing between 18.2 to 40.9 kg (40 and 90 lb) representing 13 breeds were evaluated; there were 4 sexually intact females, 21 spayed females, 4 sexually intact males, and 21 castrated males. Ages ranged from 1 to 12 years. Thirty-four dogs had no VPC; 16 dogs had between 1 and 24 VPC. The grade of arrhythmia ranged from 1 to 4, with 4 dogs having an arrhythmia with a grade > 1. Significant differences were not detected between the group of dogs with VPC and those without VPC with regard to sex, age, and minimum, maximum, or mean heart rate.
We conclude that healthy mature dogs have infrequent VPC, as detected by use of 24-hour AECG. The presence of numerous or sequential VPC may be suggestive of cardiac or systemic disease and may indicate the need for thorough clinical evaluation.
评估24小时动态心电图（AECG）用于检测健康犬室性早搏（VPC）的情况。
病例系列。
50只健康成年犬。
对每只犬进行24小时AECG检查，并评估是否存在VPC。
评估了50只体重在18.2至40.9千克（40至90磅）之间、代表13个品种的犬；其中有4只未绝育雌性犬、21只已绝育雌性犬、4只未绝育雄性犬和21只已绝育雄性犬。年龄范围为1至12岁。34只犬无VPC；16只犬有1至24个VPC。心律失常分级为1至4级，4只犬的心律失常分级>1级。在有VPC的犬组和无VPC的犬组之间，在性别、年龄以及最低、最高或平均心率方面未检测到显著差异。
我们得出结论，通过24小时AECG检测发现，健康成年犬很少出现VPC。大量或连续出现VPC可能提示心脏或全身性疾病，可能表明需要进行全面的临床评估。
