What is heart fibrillation?
cardiac fibrillation is irregular and unsynchronized contraction of the heart muscle. Because the heart rhythm - ie blood circulation - depends on synchronized muscle contraction and relaxation, its absence can disrupt normal heart function. When this occurs in the hall, it is called atrial fibrillation and is characterized by a rapid and chaotic electrical activity of heart muscle cells. Chamber fibrillation can quickly lead to death if it is not immediately treated because the chambers lose normal rhythm and stop downloading and closing circulation.
The state caused by many different diseases, heart fibrillation occurs when the muscles inside the heart irregularly download. It causes abnormal heart rhythm, also known as arrhythmias. Disabilities of the heart muscle can become one of the two upper chambers called the atrium, or in two lower chambers called the chambers. While cardiac fibrillation occurs in atriachronic health problems over time and increases the risk of stroke,It does not necessarily have to be emergency.
The normal pattern of the heart rhythm - called sinus rhythm - is controlled by electric currents that travel through the heart muscle and cause it to withdraw. Regardless of the number of heart rhythms that occur within a minute in a normal heart, the interval between rhythms remains the same at any given heart rate. During cardiac fibrillation, there are electrical signals at irregular intervals that interrupt this cycle with an unbalanced rapid rhythm of the heart. When atrial fibrillation, there is an electric current, which usually comes only from the cardioster -cylinder of the heart - node SA - instead releases from cells across the net, which prevents muscle in the current contraction of normal heart rhythm.
atrial fibrillation is the most common form of cardiac fibriluation. When the atrial cells are trembling due to a decentralized electric current, they cannot pump blood properly into the chambers. ChamberThe contractions are slower than normal atrial speed and are much slower during the tempo of the atrial fibrillation. As a result, if the atrial cells are downloaded rapidly, the chambers will have insufficient time to catch up or fully fill with blood to pump into the systemic circulation. If this condition becomes chronic, there is a risk that the wall of the muscle hall will be fibrous and the heart rhythm will remain unusual.
Chamber fibrillation is very dangerous because blood remains in the heart and is not exhausted. If the normal sinus rhythm is not restored rapidly, the chaotic chamber rhythm will retreat asystole or flat lining, causing heart death. This is often due to a heart attack or deprivation in the heart muscles, although less common events such as electric and injuries may also induction. Chamber fibrillation is reflected in the lack of pulse and unconsciousness. Patients require immediate medical treatment with an electric defibrillator to restore normal heart rhythm and many also need to needThey beat aftercare.
