Bozorgmanesh, R.; Magdesian, K. G.; Estell, Krista; Stern, J. A.; Swain, E. A.; Griffiths, L. G. (2016-01)
BACKGROUND: There is limited information on the incidence of clinical signs, concurrent illness and treatment options for atrial fibrillation (AF) in New World Camelids (NWC). OBJECTIVE: Describe clinical signs and outcome of AF in NWC. ANIMALS: Eight New World Camelids admitted with AF. METHODS: A retrospective observational study of camelids diagnosed with AF based on characteristic findings on electrocardiogram (ECG). RESULTS: All animals had an irregularly irregular heart rhythm detected on physical examination and 4 cases had obtunded mentation on admission. Three camelids were diagnosed with AF secondary to oleander intoxication, 3 animals had underlying cardiovascular disease, 1 was diagnosed with lone AF and 1 had AF diagnosed on examination for a urethral obstruction. Five of eight animals survived to discharge and nonsurvivors consisted of animals which died or were euthanized as a result of cardiovascular disease (2/8) or extra-cardiac disease unrelated to the AF (1/8). CONCLUSIONS AND CLINICAL IMPORTANCE: Atrial fibrillation occurs in NWC in association with cardiovascular disease, extra-cardiac disease or as lone AF. Amiodarone and transthoracic cardioversion were attempted in one llama with lone AF, but were unsuccessful. Atrial fibrillation was recorded in 0.1% of admissions.
