Treatment of bradycardia in horses has been historically ignored because of the motility depressant effects of nonselective antimuscarinics. This study evaluated the cardiopulmonary effects of a cardioselective (M2) muscarinic antagonist, methoctrami

Objective—To describe and compare the distribution of technetium Tc 99m (99mTc) pertechnate following intraosseous or IV injection (with or without use of a tourniquet) in the distal portion of the forelimb in standing horses. Animals—4 horses. P
