While yellow stool can be caused by sweet potatoes, carrots, and foods with yellow food coloring, it can also indicate excess fat in the stool, which can be caused by a malabsorption disorder like celiac disease, lactose intolerance, or a disorder that prevents the pancreas from providing enzymes that digest fat.
Sinus arrhythmia irregular sinus arrythmia that originates in the SA node, alternating periods of slow and rapid HR, associated with inspiration. - Normal PQRST - Inconsistent R-R intervals - normal in dogs and horses
Occlusion of the arterial blood supply to the SA node (most commonly due to a myocardial infarction or progressive coronary artery disease) can therefore cause ischaemia and cell death in the SA node. This can disrupt the electrical pacemaker function of the SA node, and can result in sick sinus syndrome.If the SA node does not function, or the impulse generated in the SA node is blocked before it travels down the electrical conduction system, a group of cells further down the heart will become its pacemaker.cclusion of the arterial blood supply to the SA node (most commonly due to a myocardial infarction or progressive coronary artery disease) can therefore cause ischaemia and cell death in the SA node.
