In some cases, late complications develop. Patients are faced with the so-called syndrome EX. There are frequent headaches and dizziness, possible loss of consciousness, shortness of breath and a sharp decrease in blood pressure.
There are several types of medical devices for maintaining heart rate. All of them perform the main function - the preservation of the physiological work of the heart. Each of the pacemakers has its own characteristics of functioning.
Today, there are many manufacturers of pacemakers on the medical equipment market. World leaders are American companies: Medtronic, St Jude, Boston Scientific, German Biotronic, Italian Sorin Group and Dutch Vitatron.
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.
