Diseases of the heart and blood vessels (cardiology)

Sinus bradycardia: causes, symptoms, treatment

The symptom, manifested as a decrease in the rhythm of contractions of the heart, does not necessarily indicate a disease. For example, when a person sleeps, the heart rate is lower than in a waking state. 

Exudation in the pericardial cavity: norm, technique of determination

If the volume of fluid in the pericardial space tends to a pathological increase, then they say about the appearance of effusion in the pericardium. During the study, a darkened echo-negative cavity is detected, mainly through subcostal access. 

Hypokinesia of the heart

In many people, this pathology is associated with changes in the myocardium after a heart attack. In this case, the passage of the contractive wave worsens on the scar site, which leads to the appearance of hypokinesia.

Aneurysm rupture of the abdominal and thoracic aorta

The cardiovascular system in which the scarlet liquid (blood) circulates, supporting the vitality of the entire human body, consists of the heart and a multitude of vessels of various sizes. 

Aneurysm rupture of the thoracic and abdominal aorta: chances of survival, treatment

The cardiovascular system in which the scarlet liquid (blood) circulates, supporting the vitality of the entire human body, consists of the heart and a multitude of vessels of various sizes. 

Syndrome of prolonged QT interval in adults and children

An interval is considered to be longer, when these figures are exceeded by 50 ms. The long interval syndrome qt (yQT) refers to ventricular arrhythmias.

Sealing of the walls of the aorta and valves

Due to such changes, the aortic wall becomes less elastic, and this can negatively affect the haemodynamic function of the aorta, which ensures continuity of oxygen-containing blood flow through other arterial vessels.

Hemopericardia of the heart

One of the adverse effects of acute myocardial infarction is hemopericard - a dangerous and often occurring condition requiring urgent medical intervention.

Changes in diffuse myocardium

The main part of the heart muscle, its middle, characterized by a special histological structure, is called the myocardium. The thickness of its walls consists of tightly connected cardiomyocytes - contractile cells of the muscle tissue of the heart, resistant to fatigue.
