Diseases of the heart and blood vessels

Heart rhythm disturbances

Parts of the heart regularly contract and relax. At first the atria contract, then the ventricles. This sequence is called the heart rhythm. In the heart are intracardial mechanisms of rhythm regulation. External regulation of heart function is conditioned by the activity of the autonomic nervous system and humoral factors. Violation of the heart rhythm leads to a disorder of the heart. Disturbances can be different: decrease in heart rate - bradycardia; Heart palpitations - tachycardia; Violation of the frequency or sequence of contractions - arrhythmia. Symptoms Attacks of palpitation. Dizziness. Nausea. Cold sweat. Convulsions. Absence of heartbeats. Cardiopalmus. Causes...

Acute rheumatism

Acute rheumatism is a complication of nasopharyngeal infection. This is a disease of connective tissue, characterized mainly by heart damage. Symptoms are diverse, since different organs are affected in this disease. Rheumatism can be accompanied by inflammation of the joints (polyarthritis), central nervous system (small chorea) disease, inflammation of the heart membranes (carditis, pericarditis). Often acute rheumatism affects children 6-15 years old, adults rarely get sick. Symptoms Fever. Subcutaneous nodules. Rash. Polyarthritis: pain in the joints, swelling and redness of the joints. Chorea: involuntary movements, grimaces. Carditis: heart failure, heart pain. 2-3 weeks...

Pericarditis

All internal organs are surrounded by a solid capsule. The heart is located in the pericardial sac, or pericardium. Pericardium is the outer shell of the heart, which consists of two sheets: the inner, covering the muscle of the heart and the outer one. Between these leaves is a very narrow cavity (pericardial cavity) containing a minimum amount of fluid. The causes of inflammation of the pericardial sac are manifold. The first symptoms of the disease are fever and severe pain. Pericarditis can be dry and exudative. In the first case, there is a deficiency of fluid in the pericardial cavity (between the leaves), in the second there is an excess. Symptoms Pain in the chest. Increased...

High blood pressure

The blood pressure of an adult is considered to be elevated if, for two consecutive days, the average figure exceeds 149/90 mmHg - this limit is set by WHO. For physicians, the lower indicator, the diastolic pressure that occurs during relaxation of the heart muscle, is more important. Optimum blood pressure -120/80 mm Hg. St., Normal - 130/85 mm Hg. Art. Hypertension is of three degrees: mild - 140-159 / 90-99 mm Hg. St, average - 160-179 / 100-109 mm Hg. Art. And high - 180-200 / 110-119 mm Hg. Art. Blood pressure is measured in millimeters of mercury (mm Hg). The diastolic pressure is 90 mm Hg. St means that the mercury column has risen to a mark of 90 mm. Modern pressure measuring...

Low blood pressure (hypotension)

The human blood pressure is lowered at a systolic blood pressure of less than 100 mm Hg. Art. And diastolic - less than 60 mm Hg. Art. However, a person can feel bad at 100 and 110 millimeters of mercury, in which case his pressure is also considered low. Hypotension is not a serious illness, and the distinct symptoms of malaise are rare. Many patients simply get dizzy or feel tired, with prolonged standing in one place, it can darken in the eyes and a fainting condition may occur. Specific form - the so-called hypotension orthostatic, associated with the gravitational attraction of the Earth and the vertical position of our body. Symptoms Fatigue. Dizziness. Darkening in the eyes....
