A medical device that maintains a heart rhythm is a complex device made from an inert medical titanium alloy. The device is a kind of mini computer that regulates the heart.
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.
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.
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.
The cardiovascular system, in which the scarlet fluid (blood) circulates, which maintains the vitality of the entire human body, consists of a heart and many vessels of various sizes.
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.
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.
One of the adverse effects of acute myocardial infarction is hemopericard - a dangerous and often occurring condition requiring urgent medical intervention.
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.
