When the primary decrease in arterial hypotension and venous pressure is determined dysfunction neurohumoral system, regulating vascular tone. Secondary hypotension observed as a symptom with various infectious diseases and intoxications, ulcers and Addison’s disease.

Symptoms and flow. Complaints may be absent. Frequently observed functional disorders of the nervous and cardiovascular systems, as manifested by headaches, dizziness, general weakness, irritability, there are unpleasant sensations and pain in the heart, palpitations, sweating. Arterial and venous pressure is lowered (blood pressure 100/50 - 80/40 mm Hg. Art., Venous pressure below 80-60 [more..]

Etiology and pathogenesis. There is a neurosis regulating blood pressure points, leading to increased muscle tone of the arterial wall, narrowing of the lumen of small arteries and arterioles and increase blood pressure. Trigger a strain neuro-psychological sphere. For secondary mechanisms include renal ischemic and endocrine factors. Ischemia kidney juxtaglomerular apparatus allocates renin, which ultimately leads to increased blood pressure.

Increased secretion of aldosterone leading to sodium retention and accumulation of fluid in the walls of arterioles, which narrows their lumen and increases the pressure.

Symptoms and flow. Hypertensive [more..]

Atherosclerosis is caused by lipid and protein metabolism, also known as arteriosclerotic vascular disease, or ASVD, or Heart and Blood Vessel Disorders. The basis of the disease is the infiltration of the arterial wall lipids, of which the most important cholesterol.

Etiology and pathogenesis. Undoubtedly, an important role in the development of the disease are neurohumoral disorders. In atherosclerosis great importance to the excess food with a rich content of animal fats and carbohydrates. However, a significant portion of blood cholesterol (about 2 / 3) is formed endogenously from acetic acid, which is an intermediate product of carbohydrate meta [more..]

Arrhythmias - heart rhythm disturbances arising as a result of various functional or organic lesions of wiring system, cardiac muscle or extracardiac nerves. Arrhythmias can be expressed not only in the change of rhythm, but also in violation of the rate of heart contractions.

Heart block - a violation of an excitation wave on the way from the sinus node to the terminal branching bundle branch block.

Blockade may be incomplete and complete and be temporary or permanent nature.

Etiology. Myocardial lesions caused by infectious diseases (rheumatic fever, diphtheria, syphilis, influenza, etc.), toxic effects, blood circulation of th [more..]
