ABSTRACT
Chalmeh A, Rezakhani A, Pourjafar
M, Sebdani MM., Electrocardiograms in lambs with foot and mouth disease, Onl J Vet Res., 24 (6):338-342, 2020. High mortality in lambs
with FMD is associated with acute myocarditis. We report electrocardiograms
(ECG) in lambs with foot and mouth (FMD) infection.
Lambs had high mortality but adults in same flocks exhibited lameness with oral
ulcers. Lambs were fevered (~40°C) with tachycardia (~200 beats/min.) tachypnea
(~80/min) suffering sudden death. Necropsy revealed gray yellow cardiac streaking with necrosis of myocardium. Based on findings we diagnosed FMD. ECG’s were recorded on bipolar base apex limb
lead with lambs standing without sedation and minimum restraint. Positive left
arm electrodes were placed over cardiac apex on the 5th left
intercostal space at the level of the elbow, right arm negative electrode on
the left jugular furrow at the top of heart base, and neutral electrode on
dorsal spine recorded in a single channel. Lambs showed no clinical signs of
cardiovascular insufficiencies such as edema and jugular distension or
pulsation. Rate, rhythm and amplitude of heart sounds and amplitude of the
peripheral pulse varied significantly. ECG showed no P waves, multiple f waves
nor irregular R-R intervals. However we recorded atrial fibrillation and
reduced ST-segments probably due to myocarditis, fever, starvation, electrolyte
imbalances, tachycardia and poor myocardial blood flow.
Key words: Foot and mouth disease, Cardiac arrhythmia, Atrial
fibrillation, ST-segment depression, Lamb.
