It then spreads down the bundle of his and then purkinje fibres to cause ventricular contraction. So when viewing the heart from the front, the direction of depolarisation is 11 o'clock to 5 o'clock. The general direction of depolarisation is known as the cardiac axis.

There are many factors that will determine how quickly, or completely you recover from your meniscal tear surgery. Key elements include your age, weight, and activity demands. The older you are, the heavier you are, the longer your recovery will be. The type of surgery you had will also impact upon your recovery. In some cases we only remove the torn piece — in general you will progress faster than someone who had sutures placed to repair the meniscus tear. Whether or not arthritis was found at the time of your meniscus surgery will also significantly influence your recovery from meniscus surgery. If you have arthritis then you are missing some or all of the cartilage on the ends of the bones. Knees with arthritis are prone to being more “cranky” during the recovery process. In those cases, a knee ice compression device can provide relief of pain/swelling. Many patients note they feel better wearing a compression sleeve during recovery. People with arthritis sometimes report improvement in their symptoms with supplements like Glucosamine, Curcumin, or Hyaluronic Acid which they believe (not proven) will smooth out the surface of the joint. Many try Tart Cherry juice because of its natural anti-inflammatory properties.. In the first few months following surgery, a knee compression sleeve does actually help many feel better. Some of the variables affecting your recovery from meniscus surgery are under your surgeon’s control. We can improve your immediate response after surgery with the use of various medications we inject within the knee before the surgery. We can also block a nerve on the side of your leg which will improve your pain for 18-24 hours after surgery. Many of you will purchase a ice compression sleeve to help minimize the pain after the surgery. In general, young, healthy active people with no evidence of osteoarthritis will experience a much more rapid recovery. Typically measured in days or a few weeks. Most people are off crutches in a day, and stop taking pain medicine within a day or two. In contrast, if you are a older, heavier and have arthritis as well as a meniscus tear, then you may take longer to recover — and may not experience a “full” recovery. This group can take weeks to months to improve. To ensure a good response to surgery, we also need to look at your health before surgery. Smoking leads to an increased infection rate and poorer healing. Diabetics with poor sugar control are at higher risk for infection and delays in healing as well. Obesity is a potential problem with anesthesia, the recovery from surgery and it may lead to more rapid progression of arthritis after surgery. The better shape you are in prior to surgery can influence your recovery.

Lesson on clinical examination of a scaphoid fracture and assessment of the anatomic snuffbox. The scaphoid bone is one of the carpal bones of the wrist. A scaphoid fracture is important to rule out due to risk of avascular necrosis, which is a compromise of bone vasculature leading to death of the bone. Scaphoid fractures can occur with a FOOSH injury. In this lesson, we discuss the clinical assessment to rule out a scaphoid fracture, including assessing and localizing the anatomic snuffbox.

The protein inside red blood cells (a) that carries oxygen to cells and carbon dioxide to the lungs is hemoglobin (b). Hemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen.

A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result. The most common location for brain aneurysms is in the network of blood vessels at the base of the brain called the circle of Willis. What causes a brain aneurysm? A person may inherit the tendency to form aneurysms, or aneurysms may develop because of hardening of the arteries (atherosclerosis) and aging. Some risk factors that can lead to brain aneurysms can be controlled, and others can't. The following risk factors may increase your risk for an aneurysm or, if you already have an aneurysm, may increase your risk of it rupturing: Family history. People who have a family history of brain aneurysms are more likely to have an aneurysm than those who don't. Previous aneurysm. People who have had a brain aneurysm are more likely to have another. Gender. Women are more likely to develop a brain aneurysm or to suffer a subarachnoid hemorrhage. Race. African Americans are more likely than whites to have a subarachnoid hemorrhage. High blood pressure. The risk of subarachnoid hemorrhage is greater in people who have a history of high blood pressure. Smoking. In addition to being a cause of high blood pressure, the use of cigarettes may greatly increase the chances of a brain aneurysm rupturing.

Bacterial vaginosis is a type of vaginal inflammation caused by the overgrowth of bacteria naturally found in the vagina, which upsets the natural balance. Women in their reproductive years are most likely to get bacterial vaginosis, but it can affect women of any age. The cause isn't completely understood, but certain activities, such as unprotected sex or frequent douching, increase your risk.

Ingrown toenails occur in both men and women. According to the National Health Services (NHS), ingrown toenails may be more common in people with sweaty feet, such as teenagers. Older people may also be at higher risk because toenails thicken with age. Many things can cause an ingrown toenail, including: cutting toenails incorrectly (Cut straight across, since angling the sides of the nail can encourage the nail to grow into the skin.) irregular, curved toenails footwear that places a lot of pressure on the big toes, such as socks and stockings that are too tight or shoes that are too tight, narrow, or flat for your feet toenail injury, including stubbing your toe, dropping something heavy on your foot, or kicking a ball repeatedly poor posture improper foot hygiene, such as not keeping your feet clean or dry genetic predisposition

Bone tumors include abnormal healing of an injury, inherited conditions, radiation therapy. It can also be caused by bone cancer or another cancer that has spread to the bone from other parts of the body. A bone tumor may cause a painless mass. Some people have dull, aching pain. And in some cases, minor injury causes a fracture near the tumor. Treatments include surgery and radiation. Some noncancerous tumors go away without treatment

Lymphoma is cancer of the lymph system (or lymphatic system), which is part of our immunity. It is characterized by the formation of solid tumors in the immune system.1 The cancer affects immune cells called lymphocytes, which are white blood cells. Diagram of the lymphatic system The lymphatic system is a system of vessels that branch back from virtually all our tissues to drain excess fluids and present foreign material to the lymph nodes. Learn more about the lymphatic system here. Statistics from the US National Cancer Institute estimate that there are nearly 20 cases of non-Hodgkin's lymphoma for every 100,000 people in the American population.2 Hodgkin's lymphoma, meanwhile, is relatively rare, with around three cases in every 100,000 people.3

Prinzmetal's or Prinzmetal angina (/ˈprɪntsmɛtəl/, sounds like "prints metal") (also known as variant angina, vasospastic angina (VSA), angina inversa, or coronary vessel spasm) is a syndrome typically consisting of angina (cardiac chest pain) at rest that occurs in cycles.

An increased prevalence of cardiovascular disease (CVD) has been found in women of childbearing age,[1] with the presence of CVD in pregnant women posing a difficult clinical scenario in which the responsibility of the treating physician extends to the unborn fetus. Profound changes occur in the maternal circulation that have the potential to adversely affect maternal and fetal health, especially in the presence of underlying heart conditions. Up to 4% of pregnancies may have cardiovascular complications despite no known prior disease. The European Society of Cardiology has published guidelines on the management of cardiovascular disease during pregnancy.[
