One very unhealthy-looking human goes into atrial fibrillation while working out in the Vegan gym. This is when the SA node is not generating coordinated electrical impulses. Instead, impulses are flowing randomly over the atrial walls eventually making their way to the AV node. The AV node then generates normal electrical impulses. The result of this appears to be normal ventricular contraction, but the atria just wiggle around, and atrial contraction is not well coordinated. Predicted effect on systolic and dastolic blood pressure Predicted effect on the EKG trace. Present both a drawing of the trace and explain how/why it is different from the normal trace.

The answer you're looking for is washing your hands. "at this late date, we all expect our doctors to wash their hands before examining us or performing an operation in order to prevent the spread of infection. surprisingly, physicians did not begin to acknowledge the lifesaving power of this simple act until 1847.it was then that dr. semmelweis began exhorting his fellow physicians at the famed vienna general hospital (allgemeines krankenhaus) to wash up before examining women about to deliver babies. his plea was far more than aesthetic; it was a matter of life and death and to prevent a deadly malady known as “childbed” or puerperal (from the latin words for child and parent) fever."
