The most common cause of ascites is cirrhosis of the liver. Drinking too much alcohol is one of the most common causes of cirrhosis of the l...
Arteriovenous Malformations Arteriovenous malformations (AVMs) happen when a group of blood vessels in your body forms incorrectly. In these malformations, arteries and veins are unusually tangled. This usually happens during development before birth or shortly after. Most people with AVMs have no initial symptoms or problems. Instead, the AVMs are often discovered when healthcare providers treat another unrelated health concern. Sometimes the rupture of one of the blood vessels in an AVM will bring the...
Automated External Defibrillator
Automated External Defibrillator When someone’s heart stops working, it is known as sudden cardiac arrest. Sudden cardiac arrest happens to many thousands of people each year.
