Ventricular fibrillation is perhaps the most deadly arrhythmia of all. In V-fib, as it is commonly called, chaotic impulses cause the ventricles of the heart to quiver instead of actively pumping blood. In a study published by the American Heart Association and titled “Evidence for multiple mechanisms in Human Ventricular Fibrillation”, researchers concluded that more...

Atrial fibrillation is a fast and chaotic beating of the atria. It mainly affects older people so the risk of developing atrial fibrillation dramatically increases past the age of sixty. Atrial fibrillation, or A-fib as it is commonly referred to, is mostly caused by wear and tear on the heart, especially for those people with chronic high blood pressure or other more...

An arrhythmia is defined as any variation from the normal rhythm in the heartbeat. When the heart beats, the electrical impulses that cause it to contract follow a specific pathway through the heart. Heart arrhythmias occur when the electrical impulses that control the heartbeat do not work properly, causing the heart to beat either too fast, too slow, or more...

Microbiology Antibiotic Resistance I. Antibiotic Resistance A. Any large population of bacteria is likely to already have a few cells that are drug resistant. 1. Due to random mutations or transfer of plasmids B. If the drug is not present, then these resistant cells will stay few in number C. When drug is present, the few cells with the resistant more...

Microbiology Control of Microbial Growth I. Terminology A. Sterilization – removal or destruction of all microbial life (including endospores) B. Disinfection – destruction of pathogens; does not remove all microbial life, but decreases the numbers 1. Disinfectant – chemical used on a surface (kitchen counter) 2. Antiseptic – chemical more...
