On the rhythm strip, the QRS might be somewhat taller or wider. One commonly seen type of polymorphic ventricular tachycardia is torsades de pointes. Torsades and other polymorphic VT are advanced rhythms which require additional expertise and expert consultation is advised.
The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
Before Dr. Benjamin Carson became the first person to successfully separate twins conjoined at the head, before he had a TV movie made about his life, before he became known for his "gifted hands" and before he became head of pediatric neurosurgery at Johns Hopkins, Ben Carson was headed down the wrong path in life.
Ebola virus disease (EVD; also Ebola hemorrhagic fever, or EHF), or simply Ebola, is a viral hemorrhagic fever of humans and other primates caused by ebolaviruses.

Overweight does not necessarily equal unhealthy. There are actually plenty of overweight people who are in excellent health (1). Conversely, many normal weight people have the metabolic problems associated with obesity (2). That’s because the fat under the skin is actually not that big of a problem (at least not from a health standpoint, it’s more of a cosmetic problem). It’s the fat in the abdominal cavity, the belly fat, that causes the biggest issues (3). If you have a lot of excess fat around your waistline, even if you’re not very heavy, then you should take some steps to get rid of it. Belly fat is usually estimated by measuring the circumference around your waist. This can easily be done at home with a simple tape measure. Anything above 40 inches (102 cm) in men and 35 inches (88 cm) in women, is known as abdominal obesity. There are actually a few proven strategies that have been shown to target the fat in the belly area more than other areas of the body.
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
Dextrocardia situs inversus refers to the heart being a mirror image situated on the right side. For all visceral organs to be mirrored, the correct term is dextrocardia situs inversus totalis. Dextrocardia is believed to occur in approximately 1 in 12,000 people.
Tests. This test tracks electrical signals from the brain. There are a number of blood tests that may be recommended as part of your epilepsy diagnosis and treatment. A positron emission tomography (PET) scan may be used to locate the part of the brain that is causing seizures.
Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function. You're most likely to contract hepatitis A from contaminated food or water or from close contact with someone who's infected. Mild cases of hepatitis A don't require treatment, and most people who are infected recover completely with no permanent liver damage. Practicing good hygiene, including washing hands frequently, is one of the best ways to protect against hepatitis A. Vaccines are available for people most at risk.
