The problem appears when there is a hole between the atria, permitting a left to right flow, or in chronic cases, from right to left. There is this case, with an eight months old Border collie female, which was taken to the Animal Physiology Laboratory of Corporación Universitaria Lasallista for an electrocardiography practice. A high QRS complex was found, suggesting a ventricular hypertrophy and leading to the performance of additional tests, which produced interauricular communication as a diagnose.esCorporación Universitaria LasallistaFacultad de Ciencias Administrativas y AgropecuariasCardiopatia congénita (Medicina Veterinaria)Cardiología (Medicina Veterinaria)Defecto septal (Medicina Veterinaria)Insuficiencia cardíaca (Medicina Veterinaria)Comunicación interatrial (Medicina Veterinaria)Article
