Older men who have a different, less-common kind of sleep apnea are more likely to develop heart problems later, research shows.
As scary as it may be, fainting – also known as syncope – is actually very common. It occurs in about one-third of the general population, and there are a number of different things that can cause someone to pass out.

If you’re being treated for a heart condition, medicine cabinet staples such as aspirin and ibuprofen may not be good for you. The same goes for certain antibiotics. Studies have found that these common medications can increase risk of bleeding, clotting, arrhythmia and even death for some heart patients. Know the risks before you take: … Read More
Many medical dramas on TV or in the movies feature defibrillation or “shock” paddles when someone is in the midst of a cardiac arrest. Similarly, an implantable cardioverter defibrillator, or ICD, is an electronic device that constantly monitors your heart rhythm.
