Use Of A Smartphone Ecg Monitor To Identify Electrocardiogram Abnormalities Due To Hyperkalemia From Urinary Obstruction In A Jacob’S Sheep, Joseph Smith
Faculty Publications and Other Works -- Large Animal Clinical Sciences
Smartphone-based ECGS present a diagnostic opportunity for large animal practice. A two year old Jacob’s sheep presented with severe hyperkalemia secondary to a urinary obstruction. Collection of an electrocardiogram from a smart-phone based device demonstrated altered waveforms typical of severe hyperkalemia. The patient was successfully managed with medical and surgical therapies. This case presents that the method of collecting a smartphone-based ECG as determined for other large animal species, may be applicable to sheep. Additionally, this report demonstrates that the smartphone-based device may be sensitive enough to detect the absence of a P wave as commonly encountered with cases of …

Appetite control is a major issue in normal growth and in suboptimal growth performance settings. A number of hormones, in particular leptin, activate or inhibit orexigenic or anorexigenic neurotransmitters within the arcuate nucleus of the hypothalamus, where feed intake regulation is integrated. Examples of appetite regulatory neurotransmitters are the stimulatory neurotransmitters neuropeptide Y (NPY), agouti-related protein (AgRP), orexin and melanin-concentrating hormone and the inhibitory neurotransmitter, melanocyte-stimulating hormone (MSH). Examination of messenger RNA (using in situ hybridization and realtime PCR) and proteins (using immunohistochemistry) for these neurotransmitters in ruminants has indicated that physiological regulation occurs in response to fasting for several …
