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.
A cortisone shot is an injection of synthetic cortisone into an inflamed area of the body. Cortisone is a powerful anti-inflammatory and is used to treat a number of syndromes with inflammation as a cause or side effect. Some syndromes are: 1  Tendonitis.2  Bursitis. Cortisone can crystallize and cause pain worse than before the shot. 2  This is called  cortisone flare  and is often brief. 3  Cortisone can cause a lightening of the skin. 4  Cortisone can damage the tissues where it is injected.
