Avaliação por eletrocardiografia contínua (holter) em cães da raça Pastor Alemão praticantes de atividade física regular / Ambulatory electrocardiography (Holter) evaluation in physically active German shepherd dogs

ABSTRACT

The pattern for ambulatory electrocardiography was evaluated in 25 healthy German Shepherd dogs. The influences of gender, age, and physical activity in HR maximum, mean, and minimum (HRmx, HRme, and HRmin, respectively) were studied. The physically active dogs (PA) showed lower HRme than sedentary animals (S) (P=0.03), whereas HRmx and HRmin were not altered (P=0.06 and P=0.65, respectively). The HRme was 80.89±13.85 for PA and 112.94±35.71 for S. No effect of gender and age on HR was observed. It is possible to state that the physical activity can modulate the sinus node of the dogs.(AU)
