Ventricular fibrillation is a very serious disturbance of the heart rhythm. Providing help too late may lead to death. The disease consists of sudden and irregular heart contractions that are not effective. The result is that the right amount of blood is not squeezed, i.e. the body is not oxygenated.
Ventricular fibrillation – what is the disease?
A properly functioning heart generates electrical impulses by itself thanks to its stimulus-conducting system. The result is the work of the individual muscles that make up the heart. Thanks to the systemic system, the organ pumps blood and oxygenates the body.
The heart is stimulated to work by three centers: the sino-atrial node (causes about 72 contractions / min), the atrioventricular node (about 50 beats / min) and the heart muscle cells (about 30 contractions / min). Depending on the source, impulses through the fibers of the stimulation system reach the heart, causing a contraction. There is a mute and another impulse.
The abnormality starts when silence is too short. Then the impulse goes to the cell through which the previous one has just passed. In this way, faster and less accurate contractions of the heart follow. The consequence is disruption of blood flow.

Ventricular fibrillation – causes
The reasons include:
- ischemic heart disease (coronary artery disease), which is changes in the coronary arteries. It results in cardiac ischemia and organ necrosis;
- previous heart problems (heart attack, valvular disease);
- heart dysfunction, that is, all kinds of cardiomyopathies;
- congenital heart defects, genetic conditions;
- long QT syndrome;
- endocrine and water-electrolyte disorders;
- taking drugs (cocaine, methamphetamines).
