Other ischemic heart diseases causing ST depression include: 1  Subendocardial ischemia or even infarction. 2  Non Q-wave myocardial infarction. 3  Reciprocal changes in acute Q-wave myocardial infarction (e.g., ST depression in leads I & aVL with acute inferior myocardial infarction) ST segment depression and T-wave changes may be seen in patients with unstable angina; Depressed but upsloping ST segment generally rules out ischemia as a cause. Also, it can be a normal variant or artifacts, such as: Pseudo-ST-depression, which is a wandering baseline due to poor skin contact of the electrode
Lymph capillaries in the tissue spaces. The lymphatic vessels, also called lymph vessels, conduct lymph between different parts of the body. They include the tubular vessels of the lymph capillaries, and the larger collecting vesselsâthe right lymphatic duct and the thoracic duct (the left lymphatic duct).
The smallest lymphatic vessels are called lymph capillaries. These vessels are closed at their ends and have very thin walls that allow interstitial fluid to flow into the capillary vessel. Once the fluid enters the lymph capillaries, it is called lymph. Lymph capillaries can be found in most areas of the body with the exceptions of the central nervous system, bone marrow, and non-vascular tissue. Lymphatic capillaries join to form lymphatic vessels. Lymphatic vessels transport lymph to lymph nodes. These structures filter lymph of pathogens, such as bacteria and viruses. Lymph nodes house immune cells called lymphocytes. These white blood cells protect against foreign organisms and damaged or cancerous cells.
