This study was carried out to determine the usefulness of standard electrocardiography for the diagnosis of early canine heartworm disease. Baseline electrocardiograms were recorded in 12 dogs. Thirty artificial Dirofilaria immitis worms were inserted in the pulmonary artery of each dog. New electrocardiograms were recorded on days 1-4, 7, 14, 21, 28 and 35 after insertion of worms. A significant attenuation of amplitude of Q wave in lead I was recorded on days 1-4, 7, 14, 21, 28 and 35; of R wave in lead II on days 21, 28 and 35; and of S wave in lead aVR on days 7, 14, 21, 28 and 35. Duration of the QRS complex in lead AVF was significantly prolonged on day 14. In 41.6% of the dogs, right axis deviation was recorded. These results suggest that for a dog whose normal baseline standard electrocardiogram is known, a comparison of the QRS complex of the baseline with those of subsequent standard electrocardiograms may suggest early canine heartworm disease when there is an attenuation of amplitude of Q wave in lead I, R wave in lead II and S wave in lead aVR. An additional indication can be right axis deviation.

Heartworm Disease

Canine heartworm disease (dirofilariosis) is a frequent parasitic disease in Greece and other para-Mediterranean countries. Immediate adulticide therapy, followed by administration of microfilaricidals, has been the mainstay of heartworm treatment. However, a more recent approach has included the requirement to killing microfilariae and Wolbachia pipientis prior to adulticide treatment. Administration of prophylactic doses of milbemycin, moxidectin, ivermectin or selamectin for 2 to 3 months, as well as of doxycycline (10 mg kg-1 bw, per os, twice daily) for a month, seems to negate the ‘susceptibility gap’ and to decrease the possibility of pulmonary thromboembolism. Moreover, an alternative protocol of adulticide therapy (2.5 mg kg-1 bw of melarsomine, intramuscularly, followed by two further injections, 24-hours apart, a month later) is considered superior to the classical one, regardless of the clinical stage of the disease.Treatment of potential complications (right heart failure or vena cava syndrome) includes administration of heart failure medication and surgical removal of adult worms. Strict exercise restriction seems to play the most important role in reducing the possibility of pulmonary thromboembolism. Alternative protocol melarsomine administration, after treatment with macrocyclic lactones and doxycycline, increases the therapeutic effect and improves prognosis in earlier stages of the disease. Continuous (or at least during the warm period of the year) preventive administration of microfilaricidals coupled with annual serological testing of animals is important for effective disease control.
