First aid for angina and myocardial infarction

Author: ambulance doctor Deryushev A.N.

Angina pectoris and myocardial infarction refer to such a common concept as ischemic heart disease. Coronary heart disease (CHD) is characterized by a mismatch between the intake of blood rich in oxygen to the cells of the myocardium and the oxygen demand for these cells. This lack of oxygen generates oxygen starvation (hypoxia), and then ischemia of cells and tissues. With a heart attack, this process ends with necrosis.

CA-blockade of the 2nd degree of the 2nd type

author: ambulance doctor Saturday AA

Sinoatrial blockade is one of the types of arrhythmia, when impulse is disturbed in the heart fibers at the place where the connection between the sinus and atrioventricular nodes occurs. It can be of several degrees and types. It depends on the level of damage to this connection.

Recovery after cardiac bypass surgery

author: doctor Bobyleva Т.R.

Heart bypass surgery, or aorto-coronary bypass surgery, is being used more and more often. The operation is performed with ischemic heart disease, in the case of a significant blockage of blood vessels that directly feed the heart muscle.

Lifespan after shunting

author: doctor Adamenko E.N.

The operation of coronary bypass surgery is the main step towards returning the patient to normal life. This operation is aimed at restoring the normal blood circulation of the heart, relieving the patient of the pain syndrome, predicting a decrease in the development of myocardial infarction and an increase in life expectancy. However, it can not completely relieve a patient of atherosclerosis.

Blockade of calcaneal spur

author: doctor Kulagina Yu.V.

One of the most common diseases of the musculoskeletal system is the calcaneal spur. This pathology is detected in 26% of patients older than 40 years, and in the age group over 70 years - already 88% of patients suffer from this disease.

Blockade of the left ventricle of the heart

author: doctor Vasil'tsov AG

The heart muscle has special properties in comparison with other organs of the human body. One of these properties is the conductivity of impulses that arise in special structures of cardiac tissue. Sometimes it happens that the impulse is not transmitted by the cells of the heart. Such states are called blockades.

Blockade of the right leg of the bundle

author: cardiologist Makarenkova T.Yu.

The blockade of the right bundle of the bundle is a pathological abnormality in the work of the conduction system of the heart, in which the electrical impulse going from the atrioventricular node to the right ventricle is slowed or absent. There are complete and partial blockade of the right leg of the village of Gis.

Complete block of left bundle branch leg

author: doctor Li V.V.

The bundle of His can be described as a collection of cardiac cells, which is divided into two parts (legs): the right and left. It is located behind the atrioventricular node. The left leg has its branches, which are connected by an anastomosis. The legs, reaching the myocardium of the ventricles, are divided into bundles of the leading cardiac cells, also called Purkinje fibers.

Partial blockade of the right bundle branch leg

author: doctor Subbota AA

The bundle of the Hyis is a system that provides the delivery of an electrical impulse to the cells of the heart, as a result of which these cells contract. The correct operation of all structures of the bundle of the Hyis provides an organized reduction of all cardiac cells, and the heart contracts as a solid organ.

Discomfort in the chest

author: doctor Mikhailovskaya Oksana

Often patients come to the doctor with a complaint about the discomfort in the chest area. There are many reasons for the occurrence of this symptom. First of all, the doctor will think about the possible myocardial ischemia, when there is insufficient supply of oxygen to the heart muscle. This happens for many reasons, primarily, the increase in cholesterol in the blood, inaccuracies in nutrition, hypertension, hereditary factors.

CA-blockade of 1 degree of 2 type

author: doctor Subbota AA

Conduction through the sinoatrial connection in the heart can be disrupted for various reasons. It can be of several degrees, each of which has a different effect on the patient's well-being. The lightest degree of this blockade is the 1st degree. This is the initial and minimal damage to the conduction system in the heart, namely, its sinoatrial connection.

CA-blockade of the 2nd degree of the 1st type

author: cardiologist Makarenkova T.Yu.

Sinoatrial blockade is a pathology of the conduction system of the heart, characterized by impaired conduction of the pulse going from the sinus node to the atria.
