The most common cause of a cardiac arrest is a life threatening abnormal heart rhythm called ventricular fibrillation (VF). Ventricular fibrillation happens when the electrical activity of your heart becomes so chaotic that the heart stops pumping and quivers or 'fibrillates' instead. There are various causes of VF.
If you have arthritis, you may have considered a cortisone shot as part of your treatment plan. These shots are not pain relievers. Cortisone is a type of steroid, a drug that lowers inflammation, which is something that can lead to less pain. Cortisone injections can be used to treat inflammation of small areas of the body, such as inflammation of a specific joint or tendon. They can also treat inflammation that is widespread throughout the body, such as with allergic reactions, asthma, and rheumatoid arthritis, which affects many joints.
1 Cortisone injections can offer fast-acting relief of inflamed muscles, joints, tendons, and bursa. 2  Complications are rare but may include infection and bleeding.  When administered by an expert, cortisone injections offer significant pain relief with only minimal discomfort.
